(Cl. 9-312) structure of the upper head rest portion and the lower body portion of the water garment; FIG. 3 depicts another embodiment yof the invention wherein the water garment has associated therewith a small sail assembly to enable the wearer to manipulate himself through the water; FIG. 4 is a cross section taken along line 4«4 showing This invention relates to a water buoyant garment such as a buoyant swimming garment in conjunction with sailing means coupled to the garment, whereby the wearer may be propelled through the water. Generally speaking, most buoyant water garments com prise iniiated, flexible devices contoured to fit the shape of the human body and are provided with fastening one type of support or well which may be used in sup porting the sail assembly; and vlFIG. 5 is a partial perspective view of another support for the sail assembly. In essence, my water garment sail-float combination comprises a single substantially rigid panel having an el liptieally shaped opening near one end through which the means for fastening the device near or about the arms, or 15 head of the wearer can be inserted, the major axis of in the region of the legs, e.g. the thighs, or by straps the ell-iptical opening running transverse to the longitudi about the waist.
