GR2 Details

The GR2 travels hard and well and complies with TSA size requirements for carry-on bags. Its simplicity, functionality, and focus on organization take inspiration from Special Forces medical rucks. It is overwhelmingly the favorite ruck of GORUCK Cadre.

Packing is fun with GR2. Seven zippered sections, two compartments that open to lie flat, and a separate bombproof laptop compartment for easy in and out at security make it ideal for long trips. Built to carry a lot of weight comfortably on your back, GR2 works when rucking heavy weight, when you need a lot of stuff, and at any of our longer Events, such as Selection and the Ascent.

Primary Features

  • Built in the USA of military-grade, highly water-resistant materials.
  • Complies with TSA size requirements for carry-on bags.
  • Three total compartments: two main compartments open flat, internal pocket layout allows for optimal organization
  • 20″ tall bombproof compartment next to your back extra reinforced to securely take any sized laptop or hydration bladder into combat  - you pick.
  • External slant pocket provides quick access to keys, travel docs, and other small items.
  • 2” x 3” VELCRO® on front allows you to customize GR2 with the patch of your choice (patch is not included).
  • Feedback from Special Forces soldiers is that due to its size and organization, it makes an ideal ruck for demolitions
  • Opens flat for easy packing and maximum organization – this is a feature found in Special Forces medical rucks.
  • Internal pockets have color-coded zippers
  • One compression strap on each side secures a sleeping pad or attaches to Brick Bag.
  • Shoulder straps are extra padded to carry heavier loads more comfortably.
  • Designed to sit high on your back, placing most of the weight on the shoulders and back (the preferred technique when rucking because these are large muscle groups).
  • 4 rows of external and internal MOLLE webbing sized to fit a GR2 Field pocket and other MOLLE friendly accessories.
  • Scars Lifetime Guarantee: Ruck Hard, Play Hard.

Laptop/Hydration Bladder Compartment

  • Separate, zipper-closed bombproof compartment next to your back protects (almost) any sized laptop or a hydration bladder. Tip: do not put a laptop and a hydration bladder in the same compartment at the same time. Water and electronics do not play well together.
  • When placing a hydration bladder in this compartment, we recommend the Low Profile Source Hydration Bladder. It is flatter than the Standard Source Hydration bladder, thereby causing much less of a bulge (when full of water) next to your back.
  • You can choose to put your hydration bladder in the main compartment instead, and carabiner it to the top MOLLE webbing. You’ll have to see how each option feels on your back and make the decision based on your preference.
  • From either compartment you can still feed your bladder hose through a VELCRO® closed opening underneath the top handle of the ruck.

Rucking (Bricks or Filler Bags) and at our Events

  • Rucking/Events: Filler bags or up to 6 wrapped bricks fit in the main compartment under the sheathed elastic retaining band. This is the preferred technique to reduce movement inside the ruck when rucking.
  • GR2 can comfortably hold more weight than any human should ruck with, well over 100 lbs.
  • Due to offering 40 Liters of space, GR2 is “overkill” at most of our Events such as GORUCK Light or The Challenge. The more room you have, the more you’ll pack. Even GORUCK Selection is possible to do with a GR1.
  • GR2’s thick padded shoulder straps make it ideal for rucking very heavy weight or when you need the space, such as at our Expeditions, GORUCK Heavy, and GORUCK Selection. Cadre Tip: if you don’t need the space, go with GR1.

Recommended Accessories

  • Hydration bladder: you can put one in either the laptop/hydration bladder compartment or in the main compartment. The Source Low Profile bladder is the preferred technique because it lies flatter. In the main compartment, either Source bladder functions well. When in doubt, go with the Low Profile.
  • GR2 Field Pocket attaches to the internal or the external MOLLE webbing and allows for additional organization with protective padding. Shadow Pockets and dry bags also allow for increased organization. Tip: colored pockets inside of a black ruck are easier to see.
  • Carabiners – attach one to the exterior to hold gloves when you’re on the move. Attach one to the interior MOLLE to hold your hydration bladder and/or Nalgene bottle.
  • Sternum Straps – when secured, these help distribute the load differently across your back and shoulders. Tip: when rucking with a sternum strap present, alternate securing it and not. This allows you to alternate weight distribution across various muscle groups.
  • Filler bags – use these to fulfill weight requirements for GORUCK Events and when rucking to train.

Primary Material: 1000Denier CORDURA® - the preferred material for Special Forces rucks due to its strength to weight ratio and durability. High stress points are strength tested at over 400 lbs.
Zippers: YKK zippers with silent, glove friendly zipper pulls constructed from gutted parachute 550 cord (gutted to reduce bulk). There is no good reason why zippers should make noise when rucking (or assaulting). Ours don’t.
Base Material: Black - Ballistic CORDURA® / Colored - Double layered 1000 D CORDURA®
Size: 12.5"W x 22”H x 9”D
Laptop: Protects all laptops, any size
Hydration: 3 liter hydration bladder (not included) hydration tube exit port found under the top handle of the ruck.
Frame Sheet: Yes
Volume: 40 liters
Weight: 5.30 pounds (2.40 kilograms)

Note: 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 but not technically waterproof. 1000D CORDURA® protects internal contents from rain – this and its strength to weight ratio are why 1000D CORDURA® is the preferred material for Special Forces rucksacks.

GR2 (40L) vs. GR1 (26L)

  • GR2 is a travel ruck aka The Traveler, GR1 is more of a training and a dayruck. So, the comparison between these two is more about your intended usage. If you want to travel the world with one ruck, go with the GR2. For GORUCK Events and as a dayruck, go with GR1. Of course GR2 will hold any and everything you need to ruck or at our Events; however, its larger liter count means it will likely hold too much stuff, more than you need. GORUCK Cadre travel all over the world with GR2’s; however, when it comes time to lead an Event, they use GR1 or whatever dayruck they packed inside their GR2 while traveling.

GR2 vs. “Hiking Bags”

  • When traveling the world (especially with a laptop and electronics), you have some decisions to make. GR2 does not have a hip belt and it does not have an external frame. These features are common on a lot of hiking bags and they help when you’re carrying very excessive loads for long distances. GR2, however, is more versatile because it’s more discreet and offers you a travel ruck that “fits in” in cities and on planes and trains and buses and you can use GR2 as a hiking ruck when you get there. Wherever there is. Most hiking bags scream tourist – GR2 screams functionality and versatility and it only screams that to you because you’ll know it once you use it. GORUCK Cadre travel the world every weekend of the year and GR2 is overwhelmingly their favorite.
