X-bionic Energizer 4.0 Mk3 Lt Rneck Ss Shirt White

Enjoy your sport more intensively than ever with patented technologies: the X-BIONIC® ENERGIZER 4.0 LIGHT SHIRT ROUND NECK SHIRT for men is an extremely lightweight undergarment with a round collar.
Worn either alone or under your shirt, it maximizes the cooling effect of your perspiration, thus increasing your endurance and boosting 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 the back, where your body can most effectively use the cooling effect. The system’s complex, three-dimensional, Y-shaped structures create a stable network of channels for intensive air exchange. It cools when you sweat and warms you when you're cold. Thermodynamic effects improve your skin-climate management.
This is achieved through interaction among numerous technologies: Sweat Traps®, Air-Conditioning Channel®, AirComPlex-Zone at the sternum and ventilation-optimized Air Guides. Tailored higher in the back area, the ergonomically optimized Ideo-Waistband keeps your shirt in place even during continual activity.
Like all X-BIONIC 4.0-generation products, this shirt is manufactured using ultra-high-resolution Retina® technology. You benefit from highly effective density, intensive functional transmission and precise separation of functional zones.
