Adjustable Hip Padz have a unique Velcro system so pads can be removed or replaced with thicker or thinner pads, allowing one boat to fit anyone. Once in place, they will not move or shift out of place. Perfect for schools or rental fleets. Available in four thicknesses, S-XL. (small for large boaters, XL for small boaters.) This eliminates the mess and fuss of gluing and sanding multiple shim pieces to achieve the perfect fit. Easy peel & stick installation. Two per set.
