Wing Neoprene Slalom Cover with Fin ProtectorWing Neoprene Slalom Cover with Fin Protector The Wing Neoprene Slalom Cover with Fin Protector is a neoprene slalom ski sleeve built with a solid fin protector moulded into the tail end. The neoprene sleeve hugs the ski to prevent rub, and the rigid fin guard shields the most fragile part of the ski from knocks in transit. Compared to a plain neoprene sock, the integrated fin protector means you don't need a separate fin cover or tail guard for short
