We spent two years prototyping and field testing Curved Straps for GR1. We came to find out that girls prefer them, that much we expected because that was the goal. The surprising part was, some dudes with big pecs do, too. Go figure.

"I felt a difference right away. To put it bluntly, my GR1 kind of squishes my boobs and this didn't. The curve of the strap definitely helped."

-Tina Streeter

"Yes I loved it, too! I normally carry an Echo for events, but I loved the fit & size of this ruck."

-Angie Rich

"The girls ruck fits like a glove! The straps are thin enough to give me great range of motion without losing blood flow to my fingertips, yet they are wide enough to still allow me to carry a heavy load comfortably. At 5'5, 125 pounds, this ruck fits my frame well and is functional!"

-Jaala Thibault

"I loved it! The difference is immediately noticeable! To me, it's much more comfortable, especially on my upper back and shoulders where I tend to feel it the most."

-Danielle Boltin

"Loved it! The closer together straps didn't land on my jog bra which usually leads to chaffing and bruising with other rucks."

-Debi Bone



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 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.

Internal/External Pockets

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.

Packing GR1

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 and 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.


The Special Forces curse clearly states, the more space you have, the more stuff you’ll pack. But, sometimes you need more stuff, and fit matters. The 21L GR1 is 18" tall and the 26L GR1 is 20" tall. The Classic 21L GR1 fits all shapes and sizes. If you’re ~6’+ and/or want 5 additional liters and 2” of additional height, go with the Larger 26L. When moving through airports, commuting, or rucking, the goal is for your ruck to be high on your back. No matter how tall you are, the 21L will rest 2” higher than the 26L.

When in doubt, go with the 21L.

Rated 5 out of 5 by from Rugged and fun I love my pink GR1. Any of my friends would tell you that we were ALL surprised when I chose to buy a pink ruck-- but I couldn't pass up such a good deal. Now that I've had it a while, I'd gladly buy it full price. This is no mere "pink"-- after two events it is still so electricly bright my buddies ask if I have to charge its batteries a night. More than all that though, true to GORUCK standards it's tough as nails and withstands my 45+ lbs weight easily. All the basic features of the GR1 are great and I use each one. Personally I don't have an opinion on the curved straps-- I'm a big girl so they are meant for someone like me, but I also never really had a problem with straight straps. Regardless, at the end of the day I'm thoroughly satisfied-- and my buddies never lose me in a crowd.

Rated 5 out of 5 by from Pink Ruck Mafia for life!!! I absolutely love my GR1 with the curved straps. It fits my body perfectly and with the added waist belt, it is comfortable to wear for many hours at a time. I don't just use this for GoRuck events, it is also great for every day use. I love the pockets and the durability of material. It looks great and feels great. I am so excited to use this for many years to come.

Rated 5 out of 5 by from Superb Color I got this pack for my fiancee for her birthday, and she absolutely loved it! The Pink is very hard to miss- it's a bit of a "Day Glow" shade of pink and your eyes burn a little bit when you look directly at it. I chose this color in hopes that if i ever lost my lady in the woods or the city- it would be easy to track her down. I also filled it with all sorts of first aid and survival equipment, a couple fire starters and a massive 3 liter bladder so she could stay hydrated. She still has plenty of room for her selfie stick and doggie poop bags and even a 30# plate (i have't attempted to sneak one in the pack just yet- but it does fit!). Buy this ruck.

Rated 5 out of 5 by from Love this pack! I use this bag for everything! I haven't done an event yet, but it's my go to for travel and every day carry. It feels great with weight in it and it's easy to find that sweet spot for different carrying situations (yay curved straps!). The pink is insanely bright, which makes it easy to find, but also shows dirt easily. Luckily, its also easy to wipe down. I wish I had the option to try a 26L GR1 with curved straps, but I am usually surprised by how much I fit in my pack. I had to contact customer service with my initial bag and they were quick and friendly. I expect this bag to last for years and only get better!
