All military pilots are familiar with the standard issue bag for their flight helmets. Its padded, small and doesn't hold much more than your helmet and a bottle of water, requiring an aviator to carry an additional bag or two. We have created a custom rucksack for a customer to alleviate this problem. Starting with the basic ALICE rucksack dimensions (slightly modified to fit an HGU-56P), and using standard ALICE hardware on the shoulder straps, we created a padded ruck that will hold all that you need in one bag. Dimensions: - 17"W x 13"D x 16"H Specifications: - 1/4" padding in the body - 1/2" padding in the bottom - 20 columns x 6 rows of MOLLE webbing on the body - 8 columns x 4 rows of MOLLE on the bottom - 6 columns x 3 rows of MOLLE on the lid - Compression straps that run vertically through the lid to the bottom, with a dual adjust side-release buckle so that you can position the buckle where it's best for you - 8" x 6" loop fastener on the lid for patches and nametapes - Drawstring closures on the top of the main pack and liner - Highly water resistant liner with hook and loop attachments on the bottom and near the top to keep it from shifting and twisting in the pack - All seams and stitches in the liner have been sealed with waterproof sealant - "S"-shaped shoulder straps with ALICE hardware for adjustment and quick-release, d-rings, a webbing loop for attaching carabiners, and ITW Web Dominators for routing cables or hydration tubes - 14' x 18" mesh map pocket inside the lid with hook and loop closure - Carry handle is made from tubular nylon webbing with a rubber hose stiffener - Pack constructed from 500D Nylon Cordura with DWR coating - Liner constructed from 420D packcloth with DWR coating
