Meet the DuraPak, a packable, lightweight waterproof backpack that uses the same cordura reinforced fabric as the DuraJak, which is a tough, featherweight jacket that provides foul weather protection. Because Endura think your kit deserves the same level of protection as you get! The innovative Cordura fabric offers rugged durability and lightweight strength, making the backpack both featherlight and resistant to abrasions, tears and scuffs.
