THERE’S THE SUMMIT. NO NEED TO CHANGE YOUR SKI UNDERWEAR ANYMORE. Designed for use on ski trips. The 3D-BionicSphere®-System uses the automatism of sweating and the chill from sweat evaporating to provide an innovative temperature regulation and duct system to ensure you maintain your ideal body temperature of 37° C. The system also works after doing sport, even after sweating. The air collects in depots which act as perfect insulation points. There is no feeling of overheating, dampness or cold at any time. Warms you when you‘re cold and cools you when you sweat. The patent-pending AirDuct™ Pads support this temperature regulation with their 3D weave technique. The 6 mm 3D woven design ensures full ventilation and comfort for the shoulder and hip area which are under strain from the backpack. Regulated compression on the upper arms and thighs for reducing muscle vibration and better blood circulation make this product a must for all ski tours.
