TURN SWEAT INTO ENERGY. Sweat is too precious to throw it all away. Our skin needs moisture to cool itself down. When moisture evaporates from the skin an evaporative cooling process takes place that we use to maintain the optimal body temperature of 37°C. Traditional technical base layers absorb moisture in its entirety so then the body steps up its sweat production. The result: Water, minerals and salts are lost. The globally unique and patented 3D-BionicSphere® System leaves a light film of sweat on the skin. The body is effectively and naturally cooled as long as it’s sweating. If sweating stops, the insulation function kicks in and less energy is demanded for temperature regulation, which leaves more energy for your activity.
