When the cooling system of the body is efficiently supported and perspiration is thus reduced, an athlete can use up to 33 per cent more energy for performance. The patented 3D Bionic Sphere System provides the right basis for this. The new Twyce running shirt contains 200 per cent more evaporation surface than conventional shirts, thus ensuring cooling and maximum improvement in performance. In addition, complex technologies are used which regulate the temperature and transport the moisture.
