This specific model is made for the Army Combat Uniform (ACU) features digital camouflage and is known for its durability and comfort, with a robust frame and multiple storage compartments. The shoulder straps for this rucksack are well-padded and come with a quick-release buckles.

The large rucksack's main body has a zippered internal load divider and openings at the top and bottom ends, to allow a sleeping bag (or other gear) to be loaded and unloaded independently without the need for an external "sleeping bag carrier."

The top flap of the large rucksack has a mesh pocket for small reference and information materials. It is secured with a hook and loop closure.

The complete large rucksack assembly has two large, removable "sustainment pouches" (included) which attach to the sides of the ruck using the same polyethylene-reinforced webbing strap and 'push dot' security snap system characteristic to the MOLLE FLC system. These sustainment pouches each contain two d-rings on the sides, which allow them to be carried by a "general-purpose sling" for alternate uses and each provides an additional 500 cubic inches' storage space
