Zeagle 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.


  • Dual redundant 55 lb lift capacity inner bladders inside a single Cordura nylon cover
  • Available with insert for mounting on metal backplates or without for mounting on Zeagle BCs
  • Capable of mounting single or twin cylinders
  • One lower dump valve per inner bladder
  • Expandable elastic nylon panel to streamline the assembly
