The OSS Redux Hydration bag combines the convenience of a drink bag with the versatility of a utility bag. Made of lightweight hydrophobic material that is durable, long-lasting and sheds water to reduce weight in wet environments. This zippered pouch designed to attach to the back of any MOLLE/PALS carrier using two MOLLE/PALS straps. The main compartment has a stretch pocket and Velcro fasteners for most drink bags. In addition, covered connection holes in the top left and right corners of the bag allow the hose of the drink bag to exit over either shoulder of the user. Additional MOLLE/PALS slots on the front and sides of the bag allow you to attach additional pouches and gear.
