The GR1 is our original and most versatile rucksack. Think of it as a dayruck or minimalist overnight ruck that protects a laptop with confidence - but lets you get in and out easily. Comfortable in cities, warzones, when rucking, and at all GORUCK Challenges, GR1 is our most popular piece of gear.


Special Forces Grade Materials

The materials we choose are proven to thrive in war. YKK Zippers perform despite Middle East sandstorms, and 1000 denier CORDURA® is the preferred material for Special Forces rucks due to its strength to weight ratio and durability.

Badass American Construction

High stress points are strength tested at over 400 lbs. GR1 is capable of holding more weight than any human should ruck with.

Bombproof Laptop Compartment

Your laptop costs $2,000, that’s why we made GR1 the best, and toughest laptop bag ever built. The separate, 17″ tall compartment next to your back is extra reinforced to securely take a laptop into combat. And you can get it in and out easily.

Frame Sheet

A removable, hard plastic frame sheet stabilizes the bombproof laptop compartment and allows you to carry more weight comfortably. If there were no frame sheet, the ruck would curl in on itself too much when you cinch it down on your shoulders.

False Bottom

We built a “false bottom” in the bombproof laptop compartment so that when you set your ruck down, your laptop won’t even notice. This adds labor to the build of the ruck, but it’s necessary for max function.

MOLLE Attachments

3 rows of external and internal MOLLE webbing let you customize GR1 how you want. MOLLE is the same system used by our Armed Forces to attach life-saving sensitive equipment, such as ammunition.

Ruck Plates

Ruck Plates (10, 20, 30, or 45 LB) work great in the laptop compartment (recommended). You can also put them in the large internal pocket or cinch them down to the internal MOLLE.

Hydration Port

Exit port for hydration bladder tube found under the top handle of the ruck.

Silent Zipper Pulls

YKK zippers with silent, glove friendly zipper pulls constructed from parachute 550 cord. There is no good reason why zippers should make noise when rucking (or assaulting). Ours don’t.

Extra Padded Straps and Handle

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

Opens Flat

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


Three internal pockets: one large elastic pocket, one large mesh zippered pocket and one small go-to zippered pocket. External slant pocket provides quick access to keys, snacks, and other small items.

2" x 3" VELCRO

Allows you to customize your GR1 with the patch of your choice.


By military-spec submersion tests, waterproof means you could repeatedly submerge something and its contents would stay entirely dry. Our rucks are highly water resistant aka rainproof.

GR1 Buzz

“The GR1 is the best backpack I have ever owned,” says Jon Wiley, lead designer for Google Search.

"Made in the USA, bomb proof, with a life time guarantee, they’re the kind of company we love to support. Enough said."

"No nonsense tactical looks that fit in just as well in the urban jungle as they do in the real one."

"These GORUCK bags are some of the best things I have seen in a long time — I’m expecting big things from the brand."

Marvel Comics' classic vigilante hero carries a GORUCK GR1 when waging his one-man war on crime.

GR1 black is authorized for wear in Army ACU uniforms and in all equivalent uniforms in all the service branches.


Short answer:

  • If you’re under 6 ft tall go with the 21L.
  • If you’re 6 ft or taller go with the 26L.

The long answer is you want a ruck that fits with the length of your back. The 21L GR1 is 18" tall and the 26L Rucker is 20" tall. That being said, using our under/over 6 ft rule usually works out pretty well.
