Top Speed Powder 5 is the hardest powder in the TSP line, and a great choice in cold conditions, for alpine skis, cross country skis and snowboards. It is popular wax due to its great durability and dry friction properties. It is made as a powder to make it easier to apply, without sacrificing the glide properties. Designed for fresh, old or artificial snow. TSP5 can be used as a stand alone race powder or as a base for liquids and wool-applied top coats.
