RVL8 snowboard binding wings. Each pair is made in Portland, Oregon with the finest quality materials. The function of the wings is to provide a solid mounting point for 3rd straps so snowboard softboot bindings can be used with skiboards. By wrapping around both sides of your upper boot, the double-hook is functional when leaning in all directions. Each pair is also fully adjustable for the rider allowing them more pressure on either the inside or outside of the leg, whichever is preferred. The RVL8 wings give you two leverage points that just cannot be achieved by the average highback.
