   Best backpack I’ve ever had. Period. Comfortable, light and durable. Love how easy it is to access water bottles too.

   Love this pack and i’m looking at buying a smaller one for the camino de Santiago this spring. i did a custom make and i was able to get longer shoulder straps (I have a large chest and the shoulder straps often cut right under my pits and doesn’t allow for any room for attachments and is uncomfortable) so being able to do this was amazing!

   AMAZING PACK! I used this for my PCT thru hike this year and barely have any complaints. This pack is incredibly durable and I didn’t have any rips or tears on the bulk of my pack (my fanny pack buckles did wear a hole through the mesh on the back but easily fixable by gear tape). It had PLENTY of room for the longer food carries or having to add in any extra warm weather gear. The side pockets were big enough to find things such as my extra water bottles, toilet paper, trowel etc. The roll down top feature was handy for compressing down my load and keeping these compact. ULA really thought of features that would help while hiking such as the drawstrings on the front and multi use of the buckles. I was able to attach my ice ax to the outside of my pack very easily using the loops at the bottom and the drawstring chord on the front.
   The only thing to note is if you don’t want to have to put your bear can in the pack vertically, you could swap out for a Y strap and the bear can won’t stay on with the regular strap it comes with. It’s definitely doable to put it in vertical, it just may take a few times to get your gear to sit right and feel comfortable. It is important to note that the weight comfortability limit is legit. We did Kearsarge pass to KMS in 5.5 days and my pack was very uncomfortable for the first 2 days. It was probably close to 30-32 pounds without water and I wanted to cry climbing up to Kearsarge pass and Forester Pass. All of it is manageable with your level of tolerance or just pretend like nothing hurts and you’ll be fine!
   I am a 5’9 female with a torso of someone who is 5’5 and legs of someone who is 6’1. I bought a small frame and small hipbelt and it worked out perfectly for me.
   Overall I will be using this pack for years to come and will purchase a new one when I tackle the CDT!

   I bought this pack in the spring but wanted several hikes with this pack before writing a review. Just finished my JMT thru hike and felt like it was time to give my rave review. On trail I noticed this pack was very popular, and for good reason. The pack fits me well based on the easy to use sizing guide. My pack was getting a bit too heavy for my liking on this recent hike with a long food carry + bear can and the pack handled it well. As a test I put 35lbs in it and it was getting a bit uncomfortable but still doable. I got the purple colour and received many compliments on it. I also bought a replacement shock cord in a different colour to give my bag a bit of customization (also very easy to use). Talking with someone on trail about the Circuit, they said they’ve noticed it’s not just a popular bag, but everyone they ask about their bag say they love it. True words! Thanks for making this bag for all our trail adventures.

   I’ve had this pack since 2015 and it is an absolute trooper. Originally, I bought it for a trip to Philmont, and fully loaded due to the sheer amount of mandatory gear I weighed in at 40 lbs after full food/water resupply. The pack is only rated to 35 lbs but it held the weight very well when it had to (although I wouldn’t exceed this). Since then, this pack has done everything you could throw at it. It went with me up Mt. Washington, sections of the AT and Mid-state trail, hunting trips, and bush wacking expeditions through laurel covered mountains. It’s also light enough to take on day trips and is small enough under minimal load that not much maneuverability is lost.

   There are a lot of highlights with this pack. For starters, I love the hip belt. Whether I’m hiking in a thin T-shirt or bundled under several layers in January, it adjusts to fit perfectly and sit where I need it to. The other thing I love about this particular pack is durability. A lot of ultralight packs don’t hold up to abuse like this one can. I’ve stuffed this thing to the brim without ever so much as busting a seam. I’ve also shoved staggering amounts of gear in the mesh pocket without so much as a hole in almost 8 Years. I’ve tugged on every strap on this thing and I’ve never once broken one cord or buckle. This is a well made, well fitting lightweight pack that also happens to be ridiculously comfortable and I can not recommend it enough.

   Q – May 31, 2023

   I submitted this review four months ago but it seems to have not been approved, so I am resending it. The loops for walking sticks are not that great. I took the bag for three months of wandering outside, sleeping outside, travelling through nine countries of differing climates. After the first month, I purchased trekking poles, and one of the four pole loops failed after the first week of use. It became removed from the stitching and the end plastic piece fell off. Another one failed after four weeks of use. Keep in mind, the poles were just sitting in there as they are meant to do, and I was just walking with the bag for the entire day. Not tugging on them, not slamming the bag against things. Maybe this could be corrected by reinforcing the stitching more on the inside? In addition to that, they loosen incredibly easily, causing the poles to fall out of the bottom loop. Had to place them back in there and tighten again about four times a day.
   The front mesh pocket, understandably, is not going to be as strong as the base material of the bag. However I found that it would get holes if there was anything in there that wasn’t very rounded or very soft and malleable, like clothing. I had a bottle of bug spray that ended up puncturing through somehow, my nail went through it once while I was searching for something in there with my hand. The plus is, the material won’t run and become a giant hole. It will get a bit bigger if stretched, but it largely stays put without running. Can easily stitch over it or apply a patch to reinforce that area.
   Another issue I had is likely a more personal one based off of my body shape, but the right side shoulder strap (I selected S shape) would dig horrible into my shoulder/clavicle. No matter how I adjusted the bag–tightened, loosened, adjust the chest strap closer, further, unclasped, adjusted the hip belt tighter, looser–it put a lot of pressure on the area and was very painful and sore for a long time. The remedy I came up with was placing my towel between the strap and my shoulder. That extra padding cushioned it enough to no longer be actively painful. It has me scared to wear the bag again for a long period of time. I might DIY the straps and add some more cushioning into the inside and see if that is all it needs.
   It is a very spacious bag and otherwise held up well for my travels.

   I discovered the ULA Circuit backpack while hiking the PCT in 2022.

   I struggled with 2 other packs prior to finding the ULA Circuit.

   Thank you Ladies who I met in the Hostel in Lone Pine who encouraged me to try on their ULA Circuit packs. Every lady in that hostel that overnight had a ULA pack, except for me.

   I called ULA and in 24 hours my new ULA Circuit arrived.

   I am a tiny sized person who has to carry the same gear as all hikers on the trail.

   ULA helped me design the right pack for my body type, weight etc.

   ULA even followed up with me after my purchase to help address any concerns.

   My ULA Circuit easily carries up to 35 lbs, fits a bear can inside the pack, and allows for great weight distribution, fully loaded.

   The easily, removable, comfortable hip belt is a huge plus because I tend to loose 20 pounds while on trail so having the right hip belt, and being able to swap it out, is essential. And it needs to be comfortable (ULA Circuit hip belt is extremely comfortable), not a cheesy, flimsy crappy belt like the one provided on my first very, very expensive non ULA pack.

   Fit, comfort, quality, customer service are all exceptional.

   Almost one year later, I still love my ULA Circuit backpack.

   Thank you Peter, who helped me. I almost quit my PCT hike because of my previous packs, but, continued on because of you, your guidance, expertise, and amazing product.

   I love my ULA Circuit.

   One year later, still full of gratitude.

   I cannot say thank you, enough.

   The pack fits like a hug. I absolutely love it. The best part of my experience with ULA was how responsive they were when I had issues. They fixed the problem immediately It’s obvious the owners really care about their relationships with customers. I am really happy I chose a Circuit

   My wife and I are in our sixties. We just started section hiking last year. After a ton of research we selected the ULA Circuit … best decision we made! We have completed over 15 section hikes, 50 days and 700km on the Bibbulmun trail in Southwestern Australia through all types of weather (except snow!). The ULA Circuit has been amazing! Super comfortable, excellent space, the right number of easy-to-access pockets … everything about it is awesome! Thank you to customer support for staying on the phone for almost 30 minutes and patiently answering our questions during our research process, it was super helpful. We highly recommend the ULA Circuit.

    This pack is a dream. Rides like a hug. Carried it for my full PCT thru and couldn’t have been happier. Amazing customer service during the shopping process too, the advice on sizing and strap shape was spot on. The BV450 bear can also does fit inside it with the flat side to your spine, which is a way more comfortable way to carry it than with the round side to your spine or having it strapped on top. Love, love, love this pack. Light but still handles weight up to 35 pounds better than any other of the leading UL packs on the market, many of which are just built badly, break down and hurt you. Most of the time I was around 25 lbs with food and water – couple liters in the side pockets. Dream carry.

    This pack does it all

    I’ve carried this pack for over 500 miles of backpacking and thru hiking, initially using it on the 272 mile Vermont Long Trail in 2021. I’ve used it in the wet Cascades of Washington, the dry and arid Sawtooths in southern Idaho, and as my travel bag when we explored Peru. This pack has done everything I have needed it to do, and I look forward to finishing out the triple tiara hikes with it as soon as I can!

    The interior has enough room for all my larger items plus food bag, and there is ample storage in the side pockets and stretchy front mesh for all the items that I need throughout the day. I’ve loaded the front mesh with as much as I can, and I haven’t noticed any wear or signs that it is about to rip. The straps (I opted for J straps) are extremely comfortable and there are plenty of adjustment straps to dial the fit in.

    The only modification I’ve made is to the adjustment straps on the hip belt. These tend to slip throughout the day, so I’ve taped them where I like them and haven’t had any issues since.

    I have an older version (2015?) that has held up very well after thousands of miles (JMT, CDT, PNT, & weekend trips). Super comfortable at loads <= 35lbs. One of the stabilizer straps (above the shoulder) needs to be retightened every few hours, and the mesh is starting to get large holes in it – but honestly suprised it's in such good shape after all the x-country abuse i've put it through!
    Looking forward to buying a new one if/when this one gets too worn out!

    Joe S. – October 7, 2022

    Just completed several weeks of training and a 240 mile NOBO JMT+ through-hike with this pack in September and can’t praise it enough. I have an older version of the pack; it is essentially the same as current except for no hydration ports, it now includes full material coverage on the pockets with drains, and the front mesh pocket is a much denser weave.

    The pack when carrying 30-35 lbs was extremely comfortable and durable. The side pockets are reachable for bottles, but it helps to have long arms and be flexible given the angle. Don’t know how anyone could use a pack without hip belt pockets, which are ample on this pack.

    Not an issue with the product, but the max weight limit is real. We carried 40 lbs with 11 days of food initially and it was too much for the pack structure, collapsing on the waist band and requiring weight be carried on the shoulders, which was uncomfortable.

    With 11 days of food, I could not put a bear canister (BV500) in the pack the first 4 days. As stated, the BV500 bear canister will not fit horizontally in the bottom of the pack and after many tetris like attempts with gear and the BV500 vertically I just couldn’t get everything in.

    I resolved this 2 ways. First, I used the top compression strap with some Velcro attached to the canister and sewn to the strap to put the canister on top on the outside. Slightly top heavy, but never had an issue with retention or the strap. Recommend packing soft material underneath the canister to support leveling.

    Second, once I no longer needed to carry excess food in the pack and had some additional room, I WAS able to put the BV500 in the top of the pack horizontally. I sat it in the top vertically then tipped it sideways and was able to get about 3 rolls of the top to close the pack and it worked extremely well.

    Hiked in the rain and snow and never had any issues. The pack has everything you need and no more. Highly recommend.

    After 6 weeks of 7hr/day hiking, hauling gear and rocks, I can say this pack holds up. I love the adjustability. Never had a problem with the hip straps despite radio/field pack/etc on my belt. My chest holster fit right between the pack straps. In the end, the middle top buckle broke at the end (don’t be carrying shovels with just the one strap, guys), a few small holes in the front fabric pocket, and there was some medium-grade fraying at the side-bottom of the pack where my emergency almond butter or something rested within rubbed on the terrain through the fabric. I can’t wait to use it much more. Even some 30% deet spray leaked in the front pocket, and there hasn’t been as issue there yet (so far). I’m hoping it’ll hold up to a gentle wash, though… it does kinda stink at this point.

    Issues: Vaguely water resistant but still gets soaking wet in any actual rain esp going through brush. Definitely requires a pack cover. Usually is only a bit damp the next day.
    Straps are uncomfortable at the mid to higher end of weight I noticed, but it is a lightweight pack so honestly you get what you ask for and it’s not that much of an issue anyway if that isn’t important to you. But I did feel it, if not get used to it.
    The loops on the shoulder straps I might want to put a bear spray or radio on are just a bit too high up/close to the face for me to have put anything there but small things.
    The three snaps to close the thing are kind cool, I like how they can be closed different ways, and are more easily repaired than a tightening loop, but they are kind of annoying if you have to keep opening/closing them multiple times a day like I had to for work.
    All the lengths of straps that let me adjust the thing, get in the way and are annoying to maneuver around at the end of the day. Need to be taped up. They got stuck in the helicopter basket frequently, but that’s a specific issue I guess.
    And the side pockets for water bottles/etc…. maybe I’m just a small person, but I could never get stuff out/PUT STUFF BACK while I was wearing the backpack. MAJOR ISSUE. I don’t want to have to take off my pack to get a sip of my water bottle, or my compass, or rock hammer! But I’m sure I’ll be able to figure it out eventually. It’s not like it’s a problem exclusive to this pack anyway. And it’s better than stuff falling out all the time.

    I would recommend.

    I love this pack! I have had two other backpacking packs (other brands) before this and both bruised my hips and collarbone. Not this pack! I’ve had it for several years now and have been on quite a few backpacking trips with it. I’ve also found it stands up well against sandstone abrasion and fits in the overhead bins as a carry-on. I love how I can put most of my day’s snacks in one hipbelt pocket and essentials in the other (sunscreen, sunglasses, chapstic, etc) and I’m good to go for miles!

    I rave about this pack to anyone who asks 🙂

    Great pack. I got my gear weight down and my old pack was overkill. Customer service is excellent and I was able to get my fit dialed. I’m barrel chested, with a reeeally long inseam and short torso. I didn’t get a lighter pack because it wouldn’t accommodate my freak dimensions, decreased comfort with heavier carry’s, and fragility with bushwhacking. I have a Catalyst and a Photon too. Simple, comfortable, and durable. Plus made in the USA. Cons are nitpicking. I wish the attachment loops were shock cord. The back panel can get tiny bits of debris in the mesh when really bushwhacking. I rarely feel it, some more of an OCD issue in my case.

    JMT Certified 2021.

    Bought this last year to replace packs over the years that I used to complete PCT section hikes. One an Osprey NOBO Mt. Hood to Canada the other a North Face SOB O Whitney Portal/Crabtree to Mexico. (Started PCT SOBO in a bad winter year in 1974 and bailed WA and restarted Cascade Locks to Tuolumne with a Frostline frame pack. Yes, I’m an older backpacker with many trips globally to boot.

    Anyway decided to close 222 miles from Yosemite to Mt Whitney and the Portal with the ULA Circuit SOBO in 2021. All I can say is I don’t mind the 5 extra ounces over a lighter weight competitor of yours. The pack easily took in the bear canister and fit my tent and gear and was the most comfortable fit for the trip. I would say one thing I wish you were around when I first started backpacking and mountaineering in New England. Kudos for making a great affordable backpack.

    I love my Circuit! I purchased my Circuit approx. 2.5 years ago and it has been a game changer. With my typical base weight being between 14-15 lbs, it is absolutely perfect. Loads are always comfortable and the adjustability on the straps is great. I am also a huge fan of the water bottle loops on the shoulder straps. Sometimes the overall pack is almost a bit too large in terms of volume capacity, but the great roll top closure makes that irrelevant as I love the flexibility the roll top provides- I still have plenty of space if I’m carrying a bear can but can roll it down as far as needed if I have less bulk on any particular trip. 10/10 highly recommend!

    I picked up a Circuit pack in Xpac VX25 Hot Lime, to carry my deep Winter gear here in NY. The material is awesome and rugged while the Hot Lime color is pretty sick, especially in winter, the color pops out nicely. My full out winter load with food, water, avalanche shovel and my MSR Lightning Accent snow shoes strapped to the back is right around 31 – 32 lbs and I had no discomfort at all while hiking up the mountains. I did remove the aluminum stray and the internal hoop suspension as I prefer my packs to be less rigid and more like a rucksack to carry. It also makes it easier to stuff the empty, limp pack inside my bivy with me at night. I usually do not use hip belts but carrying 30 + lbs and trudging through snow while hiking, I found the hip belts to be a nice luxury to have. The Circuit will definitely be my new winter pack for years to come when I need to carry that extra weight and gear. Being able to customize your own pack is also a sweet bonus that makes ULA packs that more enticing. Made here in the USA!! Enough said!

    Love love love this pack! So simple yet so versatile with its design. It may not be considered ultralight anymore these days but it’s a been proven over the years by others to being a great balance between still being lightweight but also ultra-tough. It compresses well but also expands with plenty of space for week long hauls where more food is needed or when it’s time to pack in a bear canister or when it’s winter and more insulation and layers are needed, or take some extra luxuries for a more relaxed and leisure trip and so on and so forth. I’m not a long distance through hiker but I’ve had this pack out for a week along a high route in Wyoming’s Wind River Mountains and several other weekend adventure trips all throughout Utah, both mountains and desert, rain and sun. I also love how I can remove all the frame components to be able to experiment with going frameless as the rest of my system and gear continues to evolve and become more simplified for trips it might make sense to do so.

    I love my Circuit pack! It’s comfortable! I carried close to 30 lbs in it, (I’m working at upgrading up my old-school gear!) and it was still comfortable for me for multi-day hikes here in Vermont. It was a big change for me to go to a roll-top pack, which I did to save weight. I’m used to a pack with lots of pockets. It wasn’t as challenging as I thought it might be to adjust my packing style. I did add an internal stash pocket and found this useful for keeping my hiker wallet items secure and easy to access.

    Customer service was outstanding. Peter was very patient and helped me sort out sizing and the right pack for me. I’m a 5’4″ woman and turned out I needed a medium pack to fit my torso length, which surprised me.

    The pack is high quality, well-made, and the fabric is durable, while still being light. I tried a lot of different packs on, and I’m glad I went with the ULA Circuit!

    I got my Circuit in 2012 in preparation for an AT thru hike. I used the pack on the whole trail and in the ensuing years in many more hiking adventures, including lots of trips in the Adirondack High Peaks (with a bear canister). I keep coming back to it over and over again. I just used it this past weekend in Harriman State Park on a wet December overnight.

    This pack is totally bomber. The water bottle pockets have gotten a few holes in it and after well over 3000 miles and 10 years of use the pack body almost has one hole in it where the suspension loop meets the hang loop on the top of the pack. Again, this is an extremely durable pack. Yes, it’s heavier than some other options, but for most of the trips I take I don’t mind the extra weight. I would say it carries well up to around 30 pounds or so (I know it says 35 but that’s not super ideal in my experience. In the 20-25 pound range it carries like a dream.

    Mike – November 23, 2021

    This pack is less than half the weight of my previous pack, and with a moderate load of around 30 pounds it’s the most comfortable pack I have ever owned (out of at least 5 different packs). I’m 5’6”, male and the medium was an excellent fit. I got the S straps because they lie flatter on my chest, they don’t cut into my shoulders and chest Iike the straps of some other packs. I used this for a 9 day high sierra trip, about 50% of which was off trail crossing slabs and talus. Full weight including food, water, bear canister was around 32 pounds. The pack felt extremely secure and snug even when clambering over boulders etc. I like the fact that the pack fits tightly against the back, unlike the current fashion for an air gap between the back and the pack; I feel that having the pack closer to my body means greater stability when crossing rough terrain. The fabric is surprisingly burly and stood up to being dragged over granite etc. I’m not wild about the roll top closure, but it seems pretty standard among lightweight packs. I don’t know why this pack seems so much more comfortable than other packs I’ve used; all I can say is that it it is! There are lighter packs around, but comfort is ultra-important over a multi-day trip and for me, this pack delivers. Good pre-sale advice and help by phone, which was also important to me.

    My wife and I love our Circuits. The waist belt is SO comfortable and the hip pockets are huge.
    The X-large shoulder pocket is the perfect addition. We also opted for the top Y-strap which allows for a more secure carry of a bear can. One of the best things is that even though this pack is rated at 68l capacity, it shrinks down really well — in fact, we both use them as daypacks! Amazing packs!

    Amazing Pack, Amazing Customer Service

    This company in general, and this model pack in particular are true gems. The Circuit is really such a great product, epscially when one’s top priorities are carrying comfort and weight. In my mind it really strikes that perfect balance of being light on the scale and comfy on the body. The custom options when going with XPAC really elevate it to a top shelf pack (nothing against the stock version which is a STEAL in my book).

    I initally conceived of it as a “heavy carry” / longer trip/more gear intensive/winter load hauler. However in applicaiton I found it to be incredibly versatile and nimble. In fact, it’s kind of a “quiver killer.” On two trips, where the load fit in a smaller ~40L pack , I still took the Circuit because it was far more comfortable. I’ve persoanly carried 17-27lbs with it and found it to be equally adept at both ends of the spectrum. My wife also got a circuit at the same time. On our first trip out it was an ongoing corus of “THIS PACK IS SO COMFORTABLE!” back and forth Annoying perhaps, but it was genuine.

    As for the customer service, it could not be better. I really just can’t say enough good things aobut the exeprince of working with Peter and Chris. Living in Utah it was awesome to get visit the workspace and see where the magic happens. The patience, and care that went into fielding all my quesitons and making a few tweaks is highly appreciated. Thier quick turn around time and attentiveness are a true model for any business, but a real stand out in the cottage pack industry.

    Needless to say this will not be my last pack from ULA equipment!

    Bought my Circuit in August 2021. I’ve only done a few short hikes with it to date but so far I absolutely love it. It’s comfortable, fits well, and swallows all my gear with ease. Hoping to do some serious miles with it once the covid restrictions ease. Need to agree with the other comments here – the ULA customer service is second to none. The speed and ease of communication plus their willingness to go the extra mile makes all the difference.

    Jim Schulz’s review below has many of the same elements as my review, although I bought my Circuit on-line, and Peter worked with me on the sizing (his suggestions were SPOT ON!). First pack was a Kelty external frame in the ’70s. I remember it being so comfortable – but of course I think any pack would have been comfortable in my 20’s! :-). I’ve been through them all – TNF, LowePro, Gregory, Dana, Osprey, etc. As I got older, I kept looking to save weight on my pack, but I did not like a lot of the ultra lite packs – looked like they were all built for youngsters with good backs!. Finally sprung for the Circuit, in particular for the aluminum stay, load lifters, the adjustable harness, the feature set, the long history of the pack, and finally the incredible reviews. This pack has to be one of my all time favorites – I’m just back from a 6 day trip in the Wind Rivers, the pack’s maiden voyage. The side pockets are the first ever ones that I can easily get a SmartWater bottle in and out of, the hip belt pockets have lots of room, and it’s very easy to adjust the pack. I stashed the maps, rain gear, first aid, TP and more in the outer mesh pocket for easy access. And I stashed water slippers (for crossing the rivers), my Katadyn BeFree water filter, and another water bottle in the other side pocket. Am very glad Peter suggested I get the S Straps – very comfortable for me. I like the way you can close the rolltop either via side straps, or via the 2 buckles on the rolltop. I just ordered another internal stash pocket (I don’t use the hydration bladder) to place a few more items conveniently. Highly recommended!

    I started backpacking the mountains of Montana in 1967 at the age of twelve. Since then, I have hike from Maine to Death Valley and everywhere in between. Over the years my chosen backpacks have changed as new gear and technology improved. I have seriously put to the test CampTrails, JanSport, Kletterwerks, Dana Design, Gregory, Osprey, Arcteryx, and Granite Gear. For the past three years, I have been wanting to try out a ULA Circuit or Catalyst. In July, I was passing through Logan, UT and stopped in at the ULA factory. They were extremely accommodating and fitted me with a teal colored Circuit. Two weeks later, I was testing it out in the Beartooth Wilderness as I hiked the 60 switchbacks over Sundance Pass. Most recently, I used it on a 40 mile Anaconda Pintlar Wilderness section of the CDT. In my 54 years of backpacking, the ULA hip belt is, hands down, the most comfortable and easily adjustable of all I have used. The Circuit’s large outer mesh sleeve was perfect for stashing my tent and rain jacket. The side pockets allowed easy access of my water bottles. The shoulder straps fit my frame better than any other setup. Kudos to the hardworking folks at ULA: the designers, the sewers, the packers, and the marketers. Your product is top of the line. Next on my list is a trek in the Bears Ears this September. Stay tuned.

    This review is long overdue. I thru-hiked the PCT in 2010 with a frameless Go-Lite, at times 45 on my back, watching with terrible envy the mysterious green and yellow packs flying by me. I stared at those packs-ULA Catalysts and Circuits- for 2650 miles. Since then I’ve had a Catalyst, a Photon, and recently it took me a year to decide on another Catalyst, or downsizing to a Circuit, making the necessary Lighterpack revisions to account for the reduced volume. One year it took. I went with a Circuit. This is my full endorsement of everything ULA, from the largest of packs to the smallest of accessories, right to the customer service. Peter will help you choose the right pack, and make sure it’s sized right, and if it’s not quite right, he’ll make it so. It’s best that you get your torso measured at REI- you want to get that right, but don’t buy the pack they want to sell you, just head over to the ULA website and get a Circuit. It is so well built, sturdy, and built to last with so many little tweaks that will make it truly your own. And the Original Green, ten years later, YUM YUM.

    I purchased a Circuit for a hike of the Oregon section of the PCT, just completed. My Circuit was great.

    The fit and comfort were never an issue, and I can come up with nothing of substance to complain about. I’m an old-school backpacker dipping his toes into ultralight, and I just couldn’t bear the lighter cloth-tubes-with-straps backpacks – I wanted a bit more structure and support. The Circuit is a great compromise between ultralight and too-beefy. Loaded properly with just 2 or 3 days of food, the Circuit disappeared from my thinking most of the time, staying out of my way and doing its job.

    The pouches on the hip belt are great, large enough for all of a day’s snacks on one side, small camera on the other. The rear mesh pouch gave me access to all the random items – toilet bag, water filtering bag, long sleeve layer, hat, etc. The pack’s design is minimalist but not restrictive.

    A month of continuous wear on the pack and I don’t think a stitch is out of place yet, although it does need a cleaning. I’m super pleased with this pack so far, and hope to get many more miles out of it.

    I bought my Circuit as a hiking pack/crag bag a year ago and could not be happier with it. I’m a 5’3″ woman, and really appreciate that ULA takes different bodies into account. I love that the Circuit is short and wide. It never comes up behind my head (my Osprey was always in my way while scrambling). It also makes it very easy to pack and I can just throw all my climbing gear without tetrising everything around.
    I also love that the Circuit sits flush against my back. I feel far more stable while scrambling an the weight sits very comfortably. I would also say that the 16kg limit is absolutely spot on. You can carry more than this, but 16kg is exactly the point where the weight transfers uncomfortably to your shoulders. I usually carry 12-13kg all up and barely feel that weight with the Circuit.
    In terms of fit, I’m a 5’3″ women with a stocky/curvy build, 27″ waist, 40″ hips. I got the small back length, small hipbelt, and S-straps as per the size guide. The hipbelt fits perfectly (the dual webbing is simple but effective). The back length is juuuuust short enough but I’d cut an inch or two if I could. The S-straps (while way better than J-straps) are a bit broad for me and can pinch/chafe under my arms. It’s no big issue, but I would have preferred narrower straps.
    Overall, I love my Circuit and have never seen a better female-friendly pack for hiking or climbing. My only points to note are that if you are very petite, you might have fit issues; and that maybe the front mesh could be a little stretchier. Minor points aside, the Circuit is a Goldilocks pack and I’d happily recommend it.

    I upgraded to the ULA Circuit from a very heavy, 1980’s backpack. I adore this pack. I have a very small waist and was able to customize the pack to fit my waist and torso length. Despite it’s lightness, the hip belt and shoulder straps are extremely comfortable. In fact, this pack is more comfortable than my old one, which was adorned with extra padding everywhere! I have taken it on short and long trips across the state of Montana. The dual water bottle pockets are great for carrying 2L of H20 that are easily accessible. This is a “no-frills” design in general-which is exactly what I was looking for. There are not a lot of extra pockets or pieces. The extra pieces or pockets that it does include can easily be removed for a lighter, more streamlined pack. I like this pack so much that I will roll down the top tightly and use it for day-hiking as well. I plan on taking this backpack on the John Muir Trail this August and I have full confidence in it. I will always purchase from ULA equipment from now on. Very impressed with their products and customer service.

    I bought the Circuit for my first hike on the Appalachian trail. It performed well and I am so pleased with it. Customer service is top-notch! I had some fitting questions, Peter had me send pictures of with the pack on and gave recommendations on adjustments. Turns out, I needed a small hip belt instead of the medium that I originally ordered. I was concerned because I was heading the the trail in less than a week and was not sure I could get the replacement hip belt in time. Peter assured me that he could get it to me in time, which he did. Saved the day! Thank Peter and all the folks at ULA for making my perfect pack!

    Bought this pack last spring and used it last summer. It saved 8 pounds in the pack alone for me, fit better than any pack I’ve ever had, and I was not sore at my destination nor when I came down the mountain a few days later. I’ve never been able to say that before. A life-changing backpack. The capacity was less, but that was actually good. That meant I packed lighter which was even better!

    While planning a trip to Isle Royale I decided to find ways to cut weight. This pack was 1/2 the weight of my older pack but I was apprehensive about buying online. After reading reviews about customer service I decided to go for it and ordered one. I received a call from ULA and discussed options and sizing. My pack arrived in plenty of time for my trip. I weighed in at the seaplane dock at right around 40 pounds with food. Add another 5 pounds of water and I set out of Windigo with 45 lbs for an 11 mile hike with a pack I have never worn before. (stupid right?) I could not have been happier with this pack. It wore comfortably and balanced well even at the limits of the recommended capacity. 7 day trip and never got sore spots which I normally did with my heavier more padded pack. I originally bought this for shorter warmer trips, and it is now my go to pack.

    All I can say is that I love my Circuit. When I am completely loaded up with 15 Kg, the hip belt carries almost the entire load. It is so comfprtable and I can walk effortlessly for hours while wearing it. After watching and reading all the reviews I could and also having contact with Peter, I am 100% satisified with my pack. The only small note is that I have trouble getting to my water in the side pockets, but that is mainly my range of mobility and not any fault in the design of the circuit. I just may have to do some more srtetching!! Great job to the crew at ÜLA!

    After purchasing backpacks from Osprey, Granite Gear, and REI I finally found MY backpack! I packed my Circuit, strapped it on, and never looked back. I especially love the loops for a water bottle on the front of my shoulder straps. The only thing I would improve is the capacity of the mesh pocket; once the backpack is filled and compressed I often struggle to fit other items in the mesh pocket. Give it a bit more fabric and you’d knock it out of the park with the Circuit.

    This pack is as amazing as advertised. I was skeptical of an ultralight pack being as comfortable as my super padded heavier ones. I’ve tried 4 other packs from major brands and the Circuit beats them hands down. I just hiked 25 miles over a weekend with about 28 lbs and no pain, no sore shoulders, no hip chafing, no boob chafing. I wore a tank top the entire time. With all my other packs, there’s always some evidence of the weight carried but not this time. I don’t know what magic went it making this design, but the accolades are well deserved.

    Wore this pack right out of the box for the Southern Sierra High Route. Perfect pack for the demands that trip has to offer. Stable and comfortable. One additional feature is that if you need to carry a second ULA pack on top of this one, like I did, it is simple to figure out a good buckling system that gives you a stable load. Awesome pack, I just wish the internal storage pockets were a little more user friendly to accommodate internal organization.

    As a long time backpacker I entered the world of ULA in 2015 when I wanted a more lightweight pack for the PCT. I absolutely LOVE my circuit and have been nothing but impressed with it’s durability, function, and look. Having done an entire thru-hike and multiple section hikes the pack is still trucking. I have had to replace a couple buckles here and there and sent it in once for some stitching repair but have felt like that has been totally manageable and expected with the wear and tear I have put on this pack. I have always been impressed with the customer service of ULA and the quality of their repairs. Chris and company has always gone above and beyond which is appreciated. If you want a quality product that completely is worth the price tag you will not be disappointed with the circuit. Love all the new customization options they now have as well! I almost want to order a new pack just to be able to design it w/ all the new colors!

    After a couple of trips, I can finally rate this pack as excellent. My previous pack was a Deuter, which was a great, bomb-proof pack, but it weighed almost 5lbs. The Circuit checked most of the boxes for me- comfortable, lightweight, and rugged. There are lighter packs out there, but they are fragile and/or cost twice as much as the Circuit.

    Prior to my purchase and after my purchase, I had some sizing questions and issues, and the owner was great. Quick replies to multiple emails, helping me out with all of my questions and making sure the pack fit properly. Another great thing about the company, is all the bags are sewn in the U.S. It’s a small thing, but it’s nice knowing your purchase was made by workers in the U.S. getting a fair wage and not at an overseas factory where labor laws and fair wages don’t exist.

    The only downside to the bag, and this is true for most bags not named Deuter, Gregory, REI and Osprey, is that I couldn’t try the bag on prior to purchase. I was a little apprehensive about buying a pack this way, but once again the customer service was top-notch and made all the difference.

    Just did a section hike of the AZT with my new Circuit and I am very pleased with the comfort and design of it. I have owned many packs over the years from the bigger name companies but always felt that they had too many features (weight) and didn’t quite fit me right. In my quest to lighten my load, I considered some of the more exotic materials but durability is a high priority for me. The Circuit strikes a perfect balance between being
    lightweight and durable and is so comfortable that it feels like an extension of my body. I love it! I’ll be ordering another one for my wife soon. Thanks to Chris and the team at ULA for all your efforts to provide such a great line up of packs, See you on the trail!

    I love my new backpack, the Circuit! It was such a big upgrade, I originally had a really heavy and cheaply made backpack that really hurt my back when I was on the trail. I got to test it out recently on a trail that is 3.5 miles +2000′ elevation, it handled nice uphill. The Circuit has many great features. It just fits really well, and sits perfect on my back. The straps and adjusters are right where they need to be. Easy to adjust and get all buckled in. The other reason I bought this pack was because it has a simple design , not a lot to it, it’s just what you need in the woods. Can’t wait to hit the trail again with this pack ! =D

    I bought my Circuit in 2017, for my thru of Te Araroa in NZ, and 3000+km later it’s still going strong! I’m a five foot tall woman with an unusually short torso and a slight scoliosis, and the kids’s size harness with S-straps fits perfectly and gives me a great carry. I’ve used my Circuit for stretches of up to 10 days – you can really cram a lot in without affecting comfort.

    I’ve been really impressed with the durability of this pack, as well. I do quite a bit of off-track in Australia that involves some scrub bashing and butt sliding and the fabric has proved highly resistant to abrasion and the hardwear all remains intact despite the pack being scraped, dragged and dropped!

    It was a gamble to order this pack online from the USA without a chance to try it on, but I’ve never second-guessed once it arrived. Bomb pack – it’s a favourite on all the hiker surveys for good reason. Thanks Chris, for making such fantastic gear!

    Took my new Circuit out for a weekend test. It carried my 25 lbs well. The hipbelt pockets were big enough for my snacks, sunscreen, purell, etc. This is the first roll-down top pack I’ve owned. It worked well in an all-day rain. I protected the contents in a dry bag and let the pack get wet. It didn’t soak up or hold water. The shoulder straps and hipbelt were comfortable. I really liked the water bottle bungees on the shoulder strap. I was also able to access my smartwater bottles in the side pockets without taking the pack off. I have a 21.5 in back and 36 in pants size and the large pack with large hipbelt was a good fit. I carried the pack for 26 miles and didn’t notice it. That’s the highest praise I can give a pack for comfort – I didn’t notice it on my back. Thanks.

    Amazing, lightweight, durable pack.

    I help coordinate and lead annual high school group week long backpacking trips and the Ohm is my go-to pack.

    Keep in mind that this is for carrying a relatively lightweight gear set up (I’d say max. 28 lbs to be comfortable) but I have easily carried all of my gear (I hike in the Pacific west/wet Coast where we have to be prepared for 30c sunny weather to rain/sleet/hail/snow and -4) plus the school group 1st Aid Kits, emergency lightweight tarps, etc. and it all fits comfortably in my pack.

    Honestly, the only two drawbacks to this pack is that the the top strap isn’t a Y strap (would be more stable for carrying a wet tent or bear can on top) – but not such and issue that it can warrant taking away a star from the review – but even more importantly…. I bought it a couple months before the awesome optional custom colours came available (doh!). Looks like I may need to buy a second ULA Ohm pack in the future.

    I am very happy with my ULA Circuit. The multiple options in hip-belt size and shoulder strap design means its easy to find the right size for you and my pack fits snug and comfortable. I’ve used it on day hikes in Arizona/Utah canyons with no signs of it being scrapped and scuffed by rocks. I’ve hiked 90+ miles in the Cascades with it carrying unto 28lbs with out it being uncomfortable. The hip belt pockets are awesome!! And huge, every time I think I’ve filled them but decide to put another bar or misc item in them it fits no issues. I have yet to fill one completely. The side water bottle pockets can be accessed while the pack is worn and I’ve had two 1-liter platypus bottles in one pocket and two 32oz gatorades in the other (one upside down) and the elastic cinch band works great to keep items in. The back mesh pocket easily fit my rainfly, waterproof jacket, hat, and a pair of empty water bottles on my Cascades hike. I wasn’t sure if I would like not having a top lid with storage but found that with some thoughtful packing of items inside, keeping items I’ll access while hiking in the top of the pack or in one of the other noted external pockets it was easy to adjust to it. I haven’t tried fitting a bear canister inside but the inside is spacious and fit all my gear for an 8-day hike. Another thing I was concerned with this pack is the back panel and it’s lack of ventilation compared to other packs. Yes it sits right on your back, which makes it easier to carry your load in my opinion, and does result in a sweat spot on your back, but I didn’t find it uncomfortable or excessive compared to other packs I’ve used. Overall I am really happy with this pack, would recommend it to anyone and look forward to buying ULA packs in the future.

    I wanted to love this pack. I think the support is amazing but I wish the fit was customizable for a smaller person. The small isn’t small enough for short torsos or for petite women. I’m an XS in clothes and I wish this bag came in XS too. Just a couple inches shorter in length of the pack OR making the straps adjustable to a shorter length and putting the straps closer together on the bag (or making them thinner) would have been the difference for me keeping this bag. Bummer. But it was excellent for keeping the weight on my hips and off my shoulders. I think I will find a used bag and sew up some more functional shoulder straps. FWIW, I’m 5’2″ 115lbs, torso length 15″ as measured by a backpacking pro.

    My wife and I are currently Thru-hiking the Appalachian Trail. This pack is amazing and never lets me down. It is very durable and while I see other packs on trail that look beat up, my circuit looks almost brand new. It handles and distributes weight very well and I have had it loaded up to around 40 lbs. I can not say enough good things about this pack and the quality of ULA. Right now we are 800 miles in and we are upgrading my wife’s pack to an ohm. I will leave another review about this pack when we finish, but I’m sure it will be more of the same. If you are looking for a pack that can handle most anything you throw at it for long section hike or a thru-hike, then this is the pack for you.

    Bought two of these, one for my wife and one for myself. Customer service was awesome on getting us set up with a good fit for both of us. My wife had struggled to find a good fitting pack prior to trying ULA so I was super excited for her to finally find a pack that fit well. We did our first trip with 25 pound pack (her) and 27 pound pack (me) and both agreed that the packs were very comfortable with the weight. At a water fill up I bumped up to 35 pounds for a couple of miles for a dry camp night. The pack still wore well at this weight but I was feeling it some as it was the end of the day and uphill to the site. The large side pockets are great (had a 1.3 L pot in one and water in the other). The mesh pocket in the back has a ton of room where I had my ULA rain kilt, rain coat, toilet kit, sit pad and camp shoes with room for more. We both went with the S straps and are pleased with them. All in all my wife and I are both excited about how the packs performed and look forward to many more great trips with them!

    Fantastic pack. I’ve had it 7 years, used heavily on multiple hiking/camping trips, as well as international trips (checked as baggage). No issues, no complaints.. It’s lightweight, comfortable, perfect size for all my gear, and the design is well thought out. I like how this pack fits – close to my body, very compact, comfortable, and stable feeling. My favorite pack hands down.

    This pack is amazing! Took it on a one week trip in Georgia and has no issues whatsoever. The customer service is the best. Only thing I would change is that the horizontal strap on the side was a little lower to strap a taller water bottle on the side, but I’ll bring a water bladder next time. Everything else is fantastic!.

    Really dig the Circuit. Have only backpacked once, but that once was over the Pacific Crest Trail from 4/26/18 to 9/17/18.. I started with a GG Mariposa (which was slightly lighter), however it was torn to shreds after it fell from the back of a pickup during a hitch. My wife sent me my Circuit in Chester, CA and it was perfect. Shame on me for not starting with it. A few thoughts; 1) Hip belt and zipper pockets: Top notch. The clasp on my Mariposa had broken within the first 600 miles. The clasp on the Circuit was much more robust, and survived the abuse of Northern CA, Oregon, and Washington. Additionally, the pockets were easily accessible and the belt itself was very comfortable. 2) Elastic pocket on the back: Perfecto for my tent, ground sheet, TP, & trash bag. 3) Top straps to close: Flawless. 4) Chris’ help in selecting the proper size: Spot on. He picked up my call on my first try, suggested I send him a picture, and in short order, I was back in the game.

    I did remove the metal internal frame that ran down the spine. It didn’t seem to add any value, and added a bit of weight. Will likely purchase a smaller ULA for my shorter day hikes.

    Chris McMaster, thank you for your support, and for making a super duper pack!!

    I have only carried this pack for around 35o km, a very rough estimate could be lots more or slightly less. Regardless it was exactly what I was looking for in a pack, it is very comfortable for carrying 30 lbs or less, when not gaining or loosing elevation I really like the thumb straps, The big stretchy pocket is amazing, I can store lots of essentials and snacks in the hipbelt pockets, and the most important for me, it is very easy to usethat waterbottle pockets while wearing the pack. The Cordura nylon is very durable which is important to me, I am rough on gear, and is water resistant for a long time but does wet out. The features, weight and price led me to this pack and I am very glad it was so, I couldn’t recommend it more!

    I’ve been using this pack since they first put on the market. It’s been all over the World in all types of conditions and it’s still going strong. I’ve been a Backpacker since about 1980 and had all kinds of packs Gregory osprey Terra Nova and others but this one is my all-time favorite pack for many reasons. The huge side pockets are great it can hold any size canteen or if you’re going with your wife or girlfriend you can even throw a bottle of wine in there very easily. Is very versatile, gerbil, light, and comfortable. I use my pack on a weekly basis and put about anywhere from 20 to 60 miles a weekend on my pack and I have no complaints with this one. I have since given away or sold all my other backpacks with the exception of my original golite Jam pack. And that’s because they are no longer in business and I keep it for sentimental reasons. I have a lot of memories with that backpack as well as my circuit. I would highly recommend it

    It’s probably unfair to knock off a star, but I am not currently owning a circuit pack; therefore, I can’t give it five stars. I had to return the pack, I assume during the delivery or maybe on the return, was received/returned with a broken frame that I didn’t realize while trying it out. The pack seemed to meet all my expectations when I first took a look at it (it’s a beaut.), but when a pack doesn’t feel right, it just doesn’t feel right and you can’t keep it (The broken frame, I’m sure, was a factor). I loved the color (green), organization, it seemed durable, the hand holders, and the simplicity. And as far as far customer service goes, it was great with a couple of quirks (full disclosure; I was extremely anxious about ordering a pack on-line (a little old school), and I was probably a bit of a pain) but all my concerns before purchasing and issues involving the return were worked out and I was satisfied, and if I try again, I would not hesitate to trust these guys. I wanted a pack for my future retirement thru-hikes, so I might wait until that time comes before trying again. I’m sorry it didn’t work out for me like it did everyone else, but that’s life-happy hiking.

    I bought the Circuit about 18 months ago and wanted to use it several times before writing a review. I could not be happier! I was coming from a more traditional (i.e., 4+ lbs heavier!) pack and spent significant time researching “ultralight” packs before deciding on the Circuit. I’ve used it twice on long sections on the JMT, most recently with my wife when I loaded-up the Circuit with more than usual (2+ person tent, fullsize bearcan, etc.) and it took the load easily. I love the adjustability and find I can always get the hipbelt to snug appropriately and take the load; its then easy to adjust the shoulder straps and lifters to get a comfortable fit every time. I like that the pack can cinch down and fit comfortably, no energy-sapping wiggle or wobble. The hip pockets are easily accessed, and the shoulder strap water bottle holders are super convenient. I’ve used this pack on numerous overnights as a scout leader and it has really held-up. The mesh pocket is fantastic, amazing how much stuff can get crammed in there. Could not be happier with my purchase!

    i have used many different kinds of packs in the last 50 years working and hiking in the outdoors. There have been day packs, work packs, ski packs, overnight packs, and long trip packs. Since I purchased a ULA Circuit, none of the other packs gets used. The Circuit works for everything. It is 68 liters and 41 ounces. It can handle 35 pounds or so. It weighs less than some of my day packs. It is more comfortable than the big packs. If you are in the outdoors a lot, do yourself a favor and buy a ULA pack.

    I love my Circuit pack! I walked the 550 mile Camino de Santiago with it, and it performed perfectly. I had tried many packs before my trip, and this one was by far the most comfortable. The weight sits on my hips, not my shoulders, so it’s never tiring. In fact, wearing it feels like a hug. I carried from 14-20 lbs in it, and found all the outside pockets perfect for organizing my gear. The big waist belt pockets are especially useful, as is the ability to carry water bottles on the front of the pack. I only saw one other person on my trek with a Circuit, and we agreed that our packs were the best kept equipment secret on the Camino. Thank you for designing and making this great product.

    I used this pack on my PCT thru hike with a ~12 lb base weight. Everything fit with room to spare including a bear can. 2600 miles later this pack still looks new. The pack was comfortable with loads up to ~30 lbs and water bottles were easy to retrieve from the side pockets. Hipbelt pockets are big enough to fit a phone (Galaxy 8+). I would recommend this pack for any backpacking trip. I’m 6′, 150 lbs and used a medium torso with a small belt.

    Purchased a ULA Circuit last fall. I’ve used it on three different 3 day/2 night trips and one 7 day/6night trip. It is a great pack. Well made, comfortable, very adjustable, and you can remove features you don’t plan to use (bladder sleeve, key/wallet pouch, hand loops, etc). The side pockets are large with adjustable compression, and the hipbelt pockets are awsome… great capacity and easy to open and close. Thanks for a great lightweight pack that is made to last!

    Excellent pack. Waited to review until I had used a couple times, including at Isle Royale National Park. Rides extremely well, especially with 20-25 pounds total weight – moves with the body and keeps they weight close in so you’re very stable. Excellent assistance with fit and service from the ULA crew (required a send back to correct the size which was handled perfectly.

I ordered it needing it in a hurry for a backpacking trip in the Arkansas Mountains and they rushed it too me just in time for my trip. The Circuit pack has a ton of room enough for my 4 day trip. Thank You guys so much and thanks you Chris over there. Great Company and Outstanding Customer Service.

    What a fantastic pack! I packed 20 lbs into a 4-day trip into Henry Coe State Park, which has lots of elevation change. The pack is super comfortable, even during multiple ventures off trail and in steep off-trail moves. It felt like an extension of my body rather than a heavy, bulky packs. Very well made and designed. At 5’5, 120, the s fit very well. Also, the best part: no hip bruising or pain even after 4 days, which I always experienced on my old pack after 1 day! Can’t wait to take it out on longer trips. I too wish I could strap something to the bottom, but there is overall plenty of storage. Also great customer service from the Down Works store in Santa Cruz where I bought it. Thanks for a great pack!

    I took the ULA Circuit on my PCT hike, and I was thoroughly satisfied. My gear fit nicely (heavy on first few days in the Sierra though), I LOVED how big the hipbelt pockets were, and the water bottle holders on the front straps are a lifesaver for an inflexible person like myself. This is a great pack. Do yourself and get a ULA Circuit.

    I’ll also note that one of the ice axe/pole loop plastic parts shattered when I dropped my pack, and the ULA team quickly sent me a replacement part after I emailed their support. A+ customer service.

    I recently purchased a couple ULA Circuit backpacks for my teenage boys (black, and woodland camo). I knew I needed something that’s durable and lightweight. After receiving the packs, we loaded them up with 20lb of gear. Thankfully the packs fit great, look good, and the material and construction feel like they’ll last for many years. The only negatives I could find would be nitpicks, such as wanting a smaller logo, or the pack not being able to stand on it’s own. What is a negative aspect to one person could be a positive to another. It’s great that many extra items can be removed (with the exception of the hip belt pockets). It’s amazing how long the Circuit has been around, largely unchanged.

    I have a rather long torso (21.5), almost 5.11 in height, and weigh about 180 lb. had some trouble figuring out which size to go for. long story short, went with the medium at first, but had to replace with a large at the end. but it was all worth the hassle. i picked this pack specially to carry not only light load, but also able to handle 35+/-
    lb loads in case when i need it. couldn’t be happier! great pack and great customer service! will buy again! thank you chris!

    I love my Circuit! As a tall and large woman, finding a pack that fits well and feels right is a particular challenge. The dual adjusting options on the hip belt made this the perfect pack for my odd size frame. The bonus…I can just get a new belt when I need a smaller size! I opted for the s-curve shoulder straps as well, which made it even better for me. The pack is a wonderfully simple design with the perfect number of bells and whistles to keep water handy, keep everything secure, and keep the packing sitting just right. I upgraded from a cheap starter pack to the Circuit, and I’m so glad I did! I hardly felt like I was wearing a pack, and was the envy of my hiking group. (They’re buying Circuits before our summer hike 🙂 ) Thanks ULA!

    Absolutely Perfect!

    After researching new packs for weeks and wanting something lighter than my current set up that will lay me on a Thru Hike without compromising the integrity of the pack or the comfort of my body, I decided to take the majority of people’s advice and tryt the Circuit. I was apprehensive at first buying online without trying it on and feeling it out firsthand, especially since the only pack I had ever found to fit properly was my Osprey Aura, everything else has been to large in the shoulders & Getting this today & loading up every ounce of gear I own felt so light and natural and actually fit well inside my Circuit. The fully adjustable straps, and load maximizes a perfect fit, especially for a taller/petite woman that was important. I also had asked for gear straps to be sewn in the bottom to allow me to maximize internal space, and the customer service I received was beyond exceptional. I will highly recommend to anyone that this pack stands a cut above the rest.

    Unrivaled durability and comfort

    My ULA Circuit is an amazing piece of gear. It’s performed in freezing rain and snow along the spine of the Great Smoky Mountains, hundreds of miles along the Appalachian Trail, deep within Grand Canyon, and has allowed me to comfortably carry 4-6L of H20 when needed. Once while hiking the Appalachian Trail, I stopped to rest and put my pack on top of a large boulder. Little did I know there was a GIANT yellow jacket nest under it! A minute later I was running down the trail trying to escape a swarm bigger than any I had ever seen before. The pack was covered with bees. I grabbed a dead limb about 12ft long and managed to fish the pack off the rock and drag it about 30ft down the trail mesh side down. Not a scratch and the pack still looks new a few hundred miles later. I would not want to experience this with a Dyneema Cuben Fiber pack, and you never know what the trail is going to throw at you. Bombproof!

    Ultralight yet bombproof

    This year on the PCT (2017) is a very difficult one because of the extreme snow conditions. Leaving Kennedy Meadows I had to carry crampons, an ice axe, a bear can, warm winter layers, and eleven days of food. I was able to fit all of this into my circuit, and carrying it was actually fairly comfortable.

    Two days into my Sierra snow trek I set my pack down and to my horror it slid off a cliff. The pack took a fall that would kill a person, and it cracked my bear cannister. The pack itself and all of the other gear inside it was unscathed, it survived the drop without even a single stitch tearing, and the stays were intact and unbent.

    I was humiliated to make such a dumb mistake, but the durability of my ULA pack was the reason I was able to carry on eight more days instead of having to bail.

    Comfort and convienience

    I couldn’t be happier with my new Circuit.The pack was very comfortable and adjustable right out of the box. The layout is perfect. The Circuit is well thought out. My initial impression during the first miles was that it didn’t require a break in. It fits great and feels much lighter than my old pack even when loaded with my usual 28 lbs. I was most impressed with the hip belt design. I can snug the upper of the four belt sections to angle the belt which keeps it on my hips. My old pack kept putting my upper glutes to sleep because it kept sliding down my waist. The belt pockets are fantastic. Easy to access and big! I really like the large pack pockets with the adjustable shock cord draw openings. Nothing falls out. The expanding pouch on the front will allow a ton of gear even after the main pack is as tight as a tick.
    Thanks ULA.

    Almost perfect

    The fit is great and it carries a ton of stuff. Only a couple of critiques. Would like a larger waist buckle, a way to strap stuff to the bottom, and I don’t love the way the load lifters attatch to just fabric and nothing structurally.
