ABSTRACT:
The life vest of the present invention is specifically adapted to protect a user's back. This protection is achieved by way of a rigid back support which is interconnected to the internal surface of the life vest. This interconnection is achieved by way of a series of straps secured upon the internal surface of the vest. The straps, in turn, are connected to the life jacket by way of stitching or such. Through this interconnection, the life jacket is allowed a certain degree of freedom. More specifically, the life jacket is permitted vertical movement relative to the back brace.
