Neoprene form fitting style life vest in adult large for 41-44 in. chest. Not the loose fitting nylon mesh vest, this is a more sleek fitting profile suitable for jet skiing or other water sports where you don't want a life jacket flapping around in the breeze. Heavy duty front zipper and securing buckles work perfectly. There is one small half inch seam split as shown in the last picture near the 6 on the ruler.
