A flotation device for athletic training or for hydrotherapy utilizes a vest-like member which encases buoyant members of unequal buoyancy such that a wearer is supported in water in an upright position, yet inclined slightly forward, and immersed above the shoulders. The vest is fitted to the wearer by adjustment and retaining straps and provides complete unhampered freedom of movement of the appendages whereby the user may exercise using the same biomechanical motions involved in a like exercise performed out of the water.
