The dump valves are totally redesigned to be waterproof, preventing water from entering the bladder when deflated. The exhaust valves also offer a low profile surface to reduce drag in the water. When deflated, this BCD has a low inherent buoyancy: you won’t have to lug around a lot of extra weights just to compensate for the buoyancy of the BCD itself. CE approved.
