Experience with the X-BIONIC® NECKWARMER 4.0 ARMADILLO , the world's first cut and abrasion resistant neck warmer, developed together with Swiss-Ski to reduce injuries during winter training and competitions.
Additionally,thanks to constant innovation the legendary patented 3D Bionic Sphere® System with ThermoSyphon® technology is more powerful than ever and enables adaptive temperature compensation perfectly suited to ambient conditions and your activity level. It cools when you sweat and warms when you are cold. Neck Sweat Traps® catch the sweat before it begins to flow and support the temperature regulating effect through targeted evaporation. To protect the cold-sensitive cheek area, the dense 3D structures of the ISO-Cheeks are knitted from a powerful high-tech yarn that keeps cold and draughts away from the sensitive facial skin.
