Dynafit has entirely reworked Speedskins. A technical breakthrough prevents undesirable snow build-up while also providing excellent gliding and climbing qualities. A special middle membrane stops water from being absorbed and improves the skin's edge seals. The skins are tear resistant and do not wrinkle easily. The Dynafit Stretch System provides the ideal attachment between skin and ski tail. Snow and ice is prevented from getting under the skin, which is tightly wrapped around the tip.
