UV-protected polypropylene webbing won't stretch when wet and delivers an impressive Minimum Breaking Strength (MBS) of 1,500 lbs. Custom cam buckle features dual stainless-steel springs for a strong, even bite that won't slip, ever. The strap size is prominently indicated on the buckle so there's never any guesswork. A woven name tag near the buckle lets you reclaim your straps from friends who borrow but don't return.
