A body buoy made of a continuous piece of e.g., one or more inches thick rubberized foam rubber or other buoyant material with shoulder members and arm openings and may be worn as a vest. The lower torso body buoy continues three to six inches above the waistline to give an upper section which provides increased buoyancy and stability to the wearer when in water. This holds the body higher out of the water and completely frees the arms and permits their free use. This is most useful for the wearer when working or playing water sports such as water polo or performing marine maintenance.
