Abstract

A flotation stole having a chest portion of greater capacity at one side than the other so that it will invert an unconscious wearer who is face down in the water, even though the wearer may also be wearing clothing and an immersion suit and the stole being disposed to be symmetrical below the water level to ensure that the wearer may then lie in a substantially symmetrical configuration when face up in the water, that is without one shoulder being lower than the other.
