Rad Features

We found ourselves constantly digging through our bags to get stuff in & out. Travel demands quick access & comfort. Unless you’re the kind of person that packs one pair of underwear you should have a bag that’s designed to pack it all, keep your stuff right by your side, & adapt to you while on the move.

The Inside

Stay organized w/soft fleece lined panels & dividers for modular storage. Secure down & compress stuff down w/adjustable cinch straps (sold separately).

14 different loops lining the inside allow you to cinch your stuff the way you want.

Fully Adjustable For The Right Fit

Think of the last time you thought “I’m sick of carrying this heavy freakin’ backpack.” We took inspiration from backpacking backpacks & added vertically adjustable shoulder straps for proper fit & weight distribution.

Suspension straps bring the load forward to reduce back strain.

We also added suspension straps to relieve your shoulders from some of the weight of the backpack. They bring the bag forward to bring the 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.

Let's talk packing & accessing tech/miscellaneous items then start moving to the outside of the bag.

Store stuff like a keyboard, charger, USB sticks on the inside panel that fully unzips for easy access & visibility.

Secure your laptop in a dedicated laptop pocket that fits up to the new 16" Macbook Pro.

Water bottle pocket stays flat while zipped & unzips partially or fully to fit a 40 Ounce HydroFlask.

Pockets on all outside panels of the bag (top, bottom, front, sides). Quick access to stuff like your snacks & water, rain jacket, or a travel adapter.

Great backpack

I’ve been looking for years for the ultimate backpack and without a lot of success. I think I may have just found it with this one. I’ve actually had to carefully study it to appreciate all the various features and functions. I do recommend you watch Gravel’s tutorial video on it as I found it helpful. Excellent quality and I can’t wait to hit the road with this one. It will travel the world! I would very much recommend this backpack.


Hi Sheila! Thank you for this! We are so glad you have enjoyed the backpack and the explanation videos. We are so glad it will get to travel with you! -Caitlin

First Travel Bag and Bar has been set high

I have the complete Backpack Travel System and I have to say this is probably the best investment I’ve made when it comes to trace bags. I used both my 42L bag and 11L bag on a road trip to visit family to get acclimated to using system and it was very convenient. I packed about a weeks worth of clothes, my Explorer Plus Toiletry bag, and my work laptop into 42L bag. I used the 11L bag for my digital camera, iPad, and charger cords, etc. Can’t wait to to use the system on international travel and utilize my 2L sling belt as well. Anyone that is looking to travel minimally and organized, I definitely recommend the system.

The only travel bag you need

This backpack travel system is incredible. The Gravel team did it again with a meticulously crafted travel bag. Everything was intentional here and you can tell that a lot of thought went into this bag. I already used it for a quick weekend getaway and can’t wait to take it across the globe.


Hey Bryan! THANK YOU SO MUCH for all of the kind words!! We appreciate it! Can't wait for you to have the opportunity to travel more internationally. :D -Caitlin
