ABSTRACT:
A personal flotation device includes front and rear panels secured together to form an aesthetically appealing life vest. The panels are provided with relatively thin sheets of buoyant material of sufficient buoyancy to cause a user to remain afloat while in the water. The vest is provided with an inflatable bladder which may be readily inflated to increase the buoyancy of the flotation vest. The flotation vest is also provided with a collar through which the bladder extends and serves to cause the user to float face-up when the bladder is inflated.
