Organized and Accessible

GR1 opens flat to make it easier to pack, organize, and find something when on the go. Special Forces medical rucks share a similar design. Inside you'll find 3 interior pockets: 1 large elastic pocket, 1 large mesh zippered pocket, and 1 small go-to pocket.

Bombproof Laptop Compartment

The separate compartment next to your back is extra reinforced to securely take a laptop into combat. The frame sheet adds structure and stability so it's not you computer that's keeping the GR1 in its shape. Keep your most important item of gear safe wherever you go.

GR1 26L

"GR1 26l was more bigger for me, I ordered a 26l 1000D, I think I should order a 21l, overall the design and quality was excellent, I have TAD fastpack, the TAD much heavier and smaller, so I want a bigger and lightweight, I found you web site and order the big one, but GR1 26l bigger than my expectation, it my own fault, Thanks so much."

Robust, quality, minimalist!

"This backpack exceeded my expectations greatly, very impressed with the design, quality and functionality. The 1000D Cordura material has a distinct tactile sensation, feeling organic and pleasant to touch. The zippers are robust, smooth with little resistance. Each compartment can store items with little interference into other areas, maintaining efficient capacity. I don’t mind the absence of a side water bottle pocket and found that it enhances the backpacks design. It’s also comfortable to carry, have not experienced any discomfort or abrasion issues."

Hao (5/5)

Best everyday backpack

"An excellent everyday backpack. It’s perfectly sized for daily essentials and stands out as the most comfortable backpack I’ve ever used—even compared to several well-known premium brands. The shoulder straps are exceptional, providing outstanding comfort throughout the day and heavy loads. I especially appreciate the minimalist design, which makes it versatile and easy to adapt to different needs. It’s also incredibly well built, with a durability that suggests it will last for many years to come."

Couldn’t be better!

"This is my 3rd ruck. I’ve been out training with my other ones with coworkers and friends and have given both of my other ones away. I’m keeping this one! The good news is that I’ve introduced about a dozen others to rucking! These bags are expensive, but I have to admit that I’ve never seen one wear out! I plan to keep this one for many years to come!"

Christopher W. (5/5)

"Great bag. I can’t wait to break it in as nice as my 15L Bullet. These bags are absolutely bomb proof. If your looking for a true ruck that you could from to war, to work, as a carryon while traveling to the Jiu-Jitsu mats or gym this is the bag that can do it all. Highly recommend Gorucks to everyone."

Ryan (5/5)

"Super sturdy bag. 1000d feels tough but not like it will abrade my clothes - almost supple. Great size. Minor gripes about build quality, lots of excess thread or loosening thread, uneven/skewed side molle, and a stitch run in the front panel fabric that im willing to chalk up as character. Also wish the patch matched the listing pics, but thats super minor."

Ian (4/5)

"Best GR1 varient yet! 1000D all over, with quick access pocket. Ive owned one of the first versions of fhe GR1 and 1000D is the real deal once broken in. I wear a ton of polyester or cotton blind shiets, nylon bomber iackets, M65 jackets etc. none have been roughed up by the backpack. The USA flag on the interior is a nice touch too. My only wishes are that it came with a key strap/D ring in the slash pocket; and including the chest strap would be much appreciated. I would buy again."

WD H. (5/5)

Amazing quality!

"Fantastic quality, well made, durable, and highly functional. It offers plenty of storage with multiple pockets, is water-resistant, and has ample room for my gear and essentials. This will be my go-to bag for light travel and one-bag trips."
