Big Bertha Redundant Bladder Assembly

One of our largest bladders, the Big Bertha is a dual redundant bladder assembly consisting of two independent 85 lb urethane bladders inside of a single Cordura nylon cover. Each bladder has its own airway and a single bottom dump valve that operate independently of each other. The bladder cover is a durable Cordura nylon material with an expandable elastic nylon insert on the front of the bladder to retract the bladder.
