Enjoy your sport more intensely than ever with patented technologies: the X-BIONIC ENERGIZER 4.0 LT SHIRT V NECK SHIRT for men is an extremely lightweight underwear with a V-shaped collar. This shirt maximizes the cooling effect of your sweat to extend your endurance and increase your athletic performance. You can immediately feel it on your skin. ThermoSyphon , the next generation of the legendary 3D Bionic Sphere system, works on the chest and back where your body can use the cooling effect most effectively. The systems complex three-dimensional Y-shaped structures form a stable network of channels for intensive air exchange. It cools down when you sweat, and warms you when you are cold. Thermodynamic effects improve your skin climate management. This is achieved through the interaction between numerous technologies: sweat traps, air conditioning channel, AirComPlex zone on the sternum and ventilation-optimised air ducting. The ergonomically optimised Ideo waistband is cut higher at the back and keeps your shirt in place even during constant activity. Like all products of the X-BIONIC 4.0 generation, this shirt is made with ultra-high-resolution Retina technology. They benefit from a highly effective density, intensive function transmission and precise separation of the functional zones.
