Feature Comparison

Size & Capacity

• 30L Dragonfly Pass-Thru: 1,857 cubic inches (30 liters)
• 36L Dragonfly Pass-Thru: 2,197 cubic inches (36 liters)

While both are compact, the 36L offers 6 extra liters of storage, giving you more room for bulkier gear, extra layers, or additional travel essentials. So, how much is 6 liters really anyway? Get into a comfortable space, close your eyes and breathe deep. Now imagine a cube floating peacefully in the air, it’s reflective and spinning on a corner axis, it’s 7.15 inches(18.17 cm) on all sides. Or refer to Figure 1. We generally regard it as just enough room for an extra pair of shoes.

Weights

• 30L: 31 ounces
• 36L: 33.7 ounces

Laptop Sleeve

• 30L: Fits up to a 16-inch Macbook
• 36L: Fits up to a 17-inch laptop

If you use a larger laptop or carry additional tech, the 36L might be the better option. Garrett usually takes a 36L if he’s going to be shooting content for us on a trip to allow for camera gear and clothing/toiletries. The taller side pockets on the 36L are great for camera tripods.

Storage & Organization

Both sizes feature a hidden pass-through passport pocket (8” x 9”), two internal mesh pockets, a quick-access top pocket, laptop sleeve, internal compression webbing, UltraStretch mesh on the side pockets and front mesh pocket, as well as front shock cord.

The 36L gives you more external storage due to the dimensional difference meaning the side pockets and front mesh pocket are longer than the 30L, the 36L also obviously offers more internal storage as well. 

Pass-Thru Feature for Travel

Both packs include a pass-thru sleeve that lets them securely slide over a rolling suitcase handle—perfect for frequent flyers and business travelers. Although this version of our Dragonfly pack is meant for travel, rest assured it’s still rugged enough to hit some summits if you find yourself in a mountainous locale. 

Price

• 30L Dragonfly Pass-Thru: $319.99
• 36L Dragonfly Pass-Thru: $349.99

With a $30 difference, the choice largely comes down to whether you need the extra capacity and features. 

Use Case Benefits

30L Dragonfly Pass-Thru: Best for Minimalist Travelers & Daily Carry

This version is ideal if you: Want a lightweight, compact bag for daily commuting or short trips with the option to utilize the passthru-sleeve for personal item travel paired with a roller bag.

 Travel frequently and need a sleek, organized carry-on that fits under airplane seats(personal item). Use a 15-inch laptop(16” Mac) or smaller and don’t carry too much tech. 

Prefer a minimalist approach with just the essentials.

This pack is a great fit for urban explorers, remote workers, and business travelers looking for an efficient, low-profile backpack. The Passport pocket is easy to access when the pack is on your rollerbag, and makes a great discrete pocket when you’re on the go. If you work on the go, this bag’s for you.

36L Dragonfly Pass-Thru: Best for Extended Travel & Extra Storage

This model is a better choice if you: Need a larger laptop sleeve (fits up to a 17-inch laptop). Prefer more external storage with UltraStretch™ pockets for water bottles, rain jackets, or snacks. 

Plan on using the pack for longer trips or carrying bulkier gear. 

Want extra flexibility for more clothing or shoes while traveling. Or if you carry additional gear like electronics.

With its additional storage the 36L is the best option for travelers who need just a little more space without going overboard. 

If you tend towards more leisure and luxury in your travels, you can’t go wrong with the extra storage.

Which One Should You Choose?

Choose the 30L if you want a compact, streamlined pack for daily use and short trips. Or if you prefer to travel with a small roller bag for your overhead luggage and want a sleek pack for a personal item to go under your seat. This is a perfect choice.

Choose the 36L if you need a bit more space for extended trips or bulkier gear. This is a great option for those that like to travel with “the kitchen sink” and plan on utilizing a larger capacity pack. Again, harking back to the extra pair of shoes, if you know you want to carry a little extra, go with the 36L. 

If you don’t need the rollerbag sleeve or passport pocket, our standard Dragonfly model will more than suit your needs.

Both bags offer the same high-quality Ultra™ fabric, durable design, and travel-friendly features, making them excellent choices depending on your specific needs. As always both packs are backed by our lifetime warranty. If you have any questions that this post didn’t address please contact us or leave them in the comments!
