Comfort Comes First

We took inspiration from backpacking backpacks & added vertically adjustable shoulder straps for proper fit & weight distribution.

We added suspension straps to relieve your shoulders from the weight of the backpack. These help bring the bag forward to bring center of mass inward.

Removable rigid backplate, padding, & mesh add comfort and help distribute weight properly + Hovering mesh decreases back sweat and doubles as a roller bag passthrough.

Everything I ever wanted!

I am currently on a three week trip for the first time with this backpack and I friggin love this thing. 42L provides so much space that is awesome to have. The main compartment is easy to organize with dividers and straps. Tech pocket is perfect for books and my laptop. All the details are very well thought out and designed. Yes, it’s a big bag but it’s extremely comfortable, and the built in frame provides so much stability and support. That added with the thick padding on the back and straps makes carrying for long periods a breeze even without a hip belt. Everything about it is really high quality so far. It is expensive but 100% worth it!



Austin! That's the best thing to hear! We're so PUMPED that you're loving the 42L bag. :) -Caitlin

Perfect Carry On

I was looking for a backpack that could be used as a carry on that had modular storage. I was insanely impressed with the Carry On Travel Backpack. I fit so much stuff in it (including a full-size CPAP) machine for a week away. I adore Gravel - I cannot say enough about the products.



Hi Tim! We adore you right back! Thanks so much for the support. We're stoked that you're loving your backpack!! -Caitlin

I'll never need to check a suitcase

The perfect travel backpack! Not to big on the outside, but still finds room for everything a backpacker needs!



Hey Drew! Exactly! That's how we want it! :D -Caitlin

Great flexibility

the external strap is sew to the bag which eliminate the issue of the zipper pathway.



Hi Edmund! Following up on this-- was there a problem with your bag? We are happy to send a new one. Best, Brooke

Buy it for life

The bag is perfect. Comfortable, modular, durable and spacious without sacrificing any aesthetics. Having it shipped to the hotel I was staying at was a breeze also, with prompt delivery and up-to-date tracking. This is probably the last travel bag I will ever need to buy.



Hi Jake! YES! That's what we like to hear!! -Caitlin
