|RVL8 snowboard binding wings. Each pair is handmade in Portland, Oregon using 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 wings provide a rigid mount for a set of ankle straps (optional). The RVL8 wings mount to any snowboard bindings providing the lateral support necessary to use snowboard boots and bindings with skiboards.
