Abstract

A buoyancy compensator includes a backpack assembly for holding a tank of compressed gas and an inflatable air cell which is removably attached to the backpack assembly. The backpack assembly includes a cummerbund and a shoulder harness so that the backpack assembly can be used to support a tank with or without the air cell. The cummerbund and shoulder harness support the entire weight of the tank, and the air cell is not required to support any of the load of the tank. The air cell is shaped to provide flotation in the lower back to buttocks area of the wearer and in the rib cage area.
