BETTER REGULATED. STAY FOCUSED LONGER. Do you wonder occasionally why traditional functional base layers end up clinging to the body damply despite convincingly technical-sounding material names? Simply put: It’s not just about the fibre. Rather, it’s also about the workmanship. X-BIONIC® offers three-dimensional, temperature-regulating textile technology designed to suit the demands of each part of your body. That achieves a decisive advantage: The body remains at its optimal temperature of 37 °C longer. The rider remains able to perform and concentrate longer.
