X-Bionic Neckwarmer 4.0 Patriot - Germany

Experience the performance-enhancing effect of optimal thermoregulation in the cold-sensitive areas of the head and neck with the X-BIONIC® NECKWARMER 4.0 neck warmer. The new 4.0 generation is the first to feature Retina® ultra-high-definition quality for maximum functional precision. The result is an ultra-dense knitted fabric in which the functional thermoregulatory zones are precisely positioned and can act with millimeter precision. Thanks to constant innovation, the legendary patented 3D Bionic Sphere® system with ThermoSyphon® technology is more powerful than ever, enabling adaptive temperature compensation perfectly suited to environmental conditions and activity level. It cools when you sweat and warms when you're cold. Neck Sweat Traps® captures sweat before it starts to flow and promotes a thermoregulatory effect through targeted evaporation. To protect the cold-sensitive area of the cheeks, the dense 3D structures of the ISO-Cheeks are made with a powerful high-tech yarn that keeps cold and drafts away from sensitive facial skin.
