The X-BIONIC ENERGIZER 4.0 LT SHIRT ROUND NECK SHIRT with patented technologies is a pleasantly light Decision Layer with a round neckline.

• On the chest and back, where your body exploits cooling with greater efficiency, the legendary 3D Bionic Sphere system in its latest evolution called ThermoSyphon optimizes the thermoregulation of your skin. With complex three-dimensional Y-shaped structures, for thermodynamic effects it creates a stable network of channels for intense air exchange. It cools you if you sweat and warms you if you are cold.
• And it is also favored by the interaction of numerous technologies: Sweat Traps, Air-Conditioning Channel, AirComPlex-Zone on the sternum and Air Guides with optimized ventilation.
• The Ideo-Waistband with optimized ergonomics and higher cut lines on the back keeps your shirt in place even if you make continuous movements.
• Color: white.
