Store, transport, and protect your gear with the lightweight, waterproof, unbreakable, black HPRC (High Performance Resin case) 3500F Backpack with Cubed Foam. The pack is made of TTX01 polypropylene plastic resin with a micro-textured surface to reduce scratching. The ergonomic back pad is made of fast drying antibacterial foam and was designed to be thicker in critical areas such as the shoulder blades and to provide the precise level of required support and protection. Carry the pack with the super-soft, rigid grip handle or wear with the adjustable, padded air mesh shoulder straps and waist belt. The pack features four side loops for attaching additional gear.
