High Speed 7 performs great in moderate winter conditions below the freezing point. HS7 is applied with a waxing iron on either snowboard, alpine skis, or cross-country skis. Its hardness makes it convenient to work with when waxing. This is a high quality fluor-free option. Can be used as a racing wax at low air humidity. HS7 can be used as a stand alone race wax or as a base for liquids or wool-applied top coats.
