DetailsExperience with the X-BIONIC® NECKWARMER 4.0 PATRIOT EDITION the performance-enhancing effect of optimal thermoregulation in the cold-sensitive areas of the head and neck. The new 4.0 generation is the first to feature the Retina® ultra-high definition quality for maximum precision of functionality. The result is an ultra-dense knitted fabric in which thermoregulating functional zones are precisely positioned and can act with pinpoint accuracy. 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.
