This is the Sprayskirt that made Mountain Surf famous. It has all of the features of our EZ-ON Dur-O-Ring, but with our original "Bombproof" fit and red ripcord.Mountain Surf introduced kevlar, now called Aramid, to the market as well as a myriad of other design features that have become industry "standards." Our skirts are hand made in our factory with the most durable materials available including 3mil double diamond articulated neoprene decks, 4 mil aramid fiber reinforced gussetts, and a unique semi-circular O-ring seal. This fit is guaranteed to give you the driest, most secure seal available.
