X-Bionic Invent 4.0 Running Speed Round Neck Men's Long Slave Base Layer, Black/Charcoal

The new 4.0 generation is the first to feature the Retina® ultra-high definition quality for maximum accuracy of functionality. The legendary patented 3D Bionic Sphere® System plays a decisive role in continual climate regulation with a shape-optimized surface on the chest and an extended zone on the back. It cools when you sweat and warms when you are cold. Enlarged Sweat Traps® balance the temperature through accurately targeted evaporation, and the Kidney Ribs inserted into the dense knit fabric simultaneously insulate the sensitive kidney and pelvic area. For even more wellbeing when running long distances, the innovative cut maximizes wearing comfort: the higher-cut Waistband with IDEO-Waistband and the Shoulder-Flex-Zone in the shoulder area are among the highly elastic material structures that stay in shape with every movement and prevent skin irritations caused by annoying chafing.
