The new Twin Skin Speedmax 80 is a lightweight race ski with an Air Core Carbon core made to get ambitious amateur racers to next level. Innovative Cold Base Bonding technology for optimal wax absorption and grindability provides even more speed. The skin ski features a shorter and wider skin profile designed to provide a secure kick while maintaining a quality glide. We recommend applying VAUHTI PURE SKIN CLEAN & CARE to clean the skin strips and to increase the gliding properties. To protect the base, a thin layer of wax is applied to the skis which must be removed and brushed off before the first use.
