Are you a running enthusiast? Now you can reach a new high in your running performance! Because the X-BIONIC® EFFEKTOR® 4.0 RUN SHIRT SH SL MEN maximizes your running performance with all the innovations of the new X-BIONIC 4.0 generation.
Newly integrated: ThermoSyphon® system, the next generation of the legendary patented 3D Bionic Sphere® system. Its complex 3D structure on the back and chest has internal and external air channels whose thermodynamics improve your skin climate. ThermoSyphon® cools when you sweat and warms you when you're cold. Closely spaced channels capture perspiration and transport it to evaporation-intensive regions. This maximizes cooling and increases your performance.
Your additional performance booster: X-BIONIC® Partialkompression® exerts pressure on your muscles via narrow bars, thereby reducing muscle vibration, improving the supply of oxygen and nutrients to the muscles and enabling faster regeneration – all without neglecting skin cooling.
This X-BIONIC 4.0-generation product is manufactured using ultra-high-resolution Retina® technology. You can feel the difference in its high effective density, intensive functional transfer and precisely defined functional zones.
