When deflated, the ClamRetract system helps to reduce size and drag to the minimum. Three dump valves and an inflator with a stainless steel mechanism ensure inflation and deflation is always controlled and safe; and the shape of the bladder compensates for the weight of the tank when sub merged and gives you freedom to move in any direction. The narrow air passage behind the neck is designed not to impede head movement or foul regulators and hoses when inflated.
The standard size has a waist belt with three rows of 40 cc holes; and the large size has six rows. This is a superb highperforming harness with ergonomic properties developed from advanced backpacks, and a unique variety of adjustment options to optimize both fit and comfort.
