Are you a running enthusiast? Now you can reach a new high in your running performance! Because the X-BIONIC® EFFEKTOR® 4.0 RUNNING SHIRT LONG SLEEVE MEN maximizes your running performance and endurance. The new 4.0 generation is the first to feature the Retina® ultra-high definition quality for maximum accuracy of functionality.
Newly integrated: the legendary patented 3D Bionic Sphere® System with ThermoSyphon® technology, which is more powerful than ever. 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.
