The Largest Possible Carry-On

A travel ruck that would thrive in Baghdad, NYC, and the mountains of Afghanistan. Or any mountains for that matter. It’s big and tough and when you get there, make the most of it.

The Bottom MOLLE webbing on the GR3® integrates with the Compression Tough Bag to store sleeping bags or dirty clothes and shoes.


Opens Flat

Easy to pack and organize. Special Forces medical rucks share a similar design.

Silent Zipper Pulls

YKK zippers with silent, glove friendly zipper pulls constructed from parachute 550 cord.

Bombproof Laptop Compartment

The separate compartment next to your back is extra reinforced to securely take a laptop into combat.

Padded Handles

Padded top handle and 2 padded side handles, perfect for carrying through the airport or pulling out of the overhead bin.

Extra Padded Straps

Shoulder straps are extra padded to carry heavier loads more comfortably.

Multiple Pockets

3 interior pockets: 2 large mesh zippered pockets and 1 small go-to zippered pocket. External slant pocket for quick access to small items.

Integrated Removable Hip Belt

Hip belts help spread the load across your hips. It integrates into the back panel and is easily removable for when you want to be more discreet.

MOLLE Attachments

4 rows of MOLLE on the front and 2 on the bottom built for the GR3 Tough bag to store your sleeping bag.

Compression Straps

2 compression straps on each side allows you to pack the bag full then cinch the straps down and keep the ruck closer to your back.

TSA Carry-On Compliant

The largest possible carry-on size at 45L. Pack everything you need and it still fits in the overhead compartment.

Interior Velcro & MOLLE

Velcro back panel is perfect for use with VELCRO acccessories or customize with your patches.

Optimized for Hydration

Clip your hydration bladder into the interior d-ring with a carabiner and feed the hose through the exit port under the top handle of the ruck.

4+ Years Later, GR3 Was Finally Ready
The goal was pretty simple, as goals are. Build a travel ruck that would thrive in Baghdad, NYC, and the mountains of Afghanistan. Or any mountains for that matter.




45L GR3® is the largest possible carry-on ruck - and has a removable yet integrated padded hip belt. Short trips = no hip belt. Long journeys with big loads, maybe even climbing a mountain = you’ll be glad you have the option. GR2® travels great and forces organization via 6 internal pockets, GR3® has one main large compartment (with 3 pockets) and works better for larger items like shoes and boots, and hiking equipment. GR1® is an ideal dayruck, not really in the same category but shown for sizing because it’s our original rucksack.



The 45L GR3® navigates the airports, cobblestone roads, and trails you take to get to the city center, the mountaintop, or both.
