What the IWA requires is a 100 MPH rated, USCG approved life vest. If you look at the specifications on the inside a life jacket, it will give a MPH rating of 50 or 100. You used to be able to tell by the amount of straps it had, 4 strap vests were the 100 MPH ones, but now you really have to look at the inside of the vest to be sure.
