X-Bionic Radiactor 4.0

Trust in the thermoregulating effect of the X-Bionic Radiactor 4.0 Pants even in extreme cold, while enjoying the unparalleled comfort of their super lightweight design. This Decision Layer is made from an ultra-dense knit with reduced volume, offering full functionality at a pleasantly low weight. Functional zones with temperature-balancing and protective effects are precisely positioned to enhance your performance. The highly effective temperature-regulating properties on cold winter days are thanks to a heat-reflecting high-tech fiber. The patented 3D Bionic Sphere System, enhanced by ThermoSyphons technology, is stronger than ever and further supports highly adaptive thermoregulation: complex 3D structures and Y-shaped elements maximize air exchange, cool when you sweat, and warm when you freeze – now even faster.
