Trust in the thermoregulating effect of the X-Bionic Radiactor 4.0 Pants even in extreme cold and enjoy the comfort of their super lightweight construction. This Decision Layer is made from an ultra-dense knit with a reduced volume that offers full functionality at a low weight. Functional zones with temperature-balancing and protective effects are precisely positioned to enhance your performance. The patented 3D Bionic Sphere System, now stronger than ever thanks to the newly developed ThermoSyphon technology, further supports highly adaptive thermoregulation: complex 3D structures and Y-shaped elements maximize air exchange, cooling when you sweat and warming when you freeze – now even faster and more efficiently than you are already used to.
