Armored pockets work with our packs and most other packs on the market. These ultralight pockets with foam padding attach to a pack"s side, front or lid compression straps, offering you extra room, protection and convenience; they can also function as a stand-alone packing system. They feature a water-resistant YKK zipper, with the protection of a "garage" that the slider parks in. The fabrics are ultralight 70-denier ripstop Hybrid sil-nylon Cordura and 210-denier nylon Cordura.
