Underwear
COOLS WHEN YOU‘RE SWEATING AND WARMS WHEN YOU‘RE FREEZING. The cooling effect of X-BIONIC® Underwear starts working when you start sweating. A sophisticated temperature regulation system with a reliable kick-start: your sweat! You know the feeling. You‘re sweaty and then come the goose bumps. Your body sets off an alarm: risk of chill! In the recovery phase when you are not sweating, the integrated air chambers in the 3D BionicSphere®-System act as insulation.
