Abstract
A flotation collar includes an exterior cover and a bladder with two cells separated by a baffle. The exterior cover includes circumferential cover zippers which unzip if the bladder is inflated, and bottle access zippers to allow, for example, CO2 bottles to be removed and replaced. Each cell has a manual inflation valve stem for manual inflation, and an automatic inflation valve stem for automatic inflation by the bottles. The baffle forms a vertical separation in a neck portion of the bladder, and a diagonal separation in lower portions of the bladder. The vertical separation allow either cell to fill the neck portion of the bladder if the other cell is deflated, to adequately carry the wearer's head above water, and the diagonal separation allows either cell in the lower portions of the bladder to retain sufficient volume if the other cell is deflated, to provide auto-rotation of the wearer.
