The Patrol BC is an impressively light weight, rear inflation BC that is anatomically designed for maximum comfort and durability. The special air cell compression strap guarantees extra quick deflation and volume control. The ultralight rigid back plate with its integrated carrying handle ensures optimal stability. The Patrol also features Cressi s Flat-Lock-Aid integrated weight system that makes it easy to release the pockets. There are 3 pressure relief valves: one on the upper part of the hose, one valve on the right-hand side of the shoulder and a third on the lower right-hand side of the air cell. The Patrol also features plastic d-rings to help reduce weight and the shoulder and waist harness are fully adjustable to one full size up or down from the stated size.
