X-Bionic Radiactor 4.0 Ladies Functional Underwear

Trust in the outstanding thermoregulating effect of the X-Bionic Radiactor 4.0 Shirt Round Neck LG SL even in extreme cold, while enjoying the unparalleled comfort of its super lightweight construction. The ultra-dense knit provides functional zones with temperature-regulating and protective effects, all within a reduced volume that ensures full functionality at a pleasantly low weight. These zones 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’re cold – now even faster and more efficiently than you’re used to.
