Ride to the top with the latest Effektor technology! The X-BIONIC® EFFEKTOR® 4.0 BIKE ZIP SHIRT SH SL MEN of the new X-BIONIC 4.0 generation brings cycling enthusiasts into the lead even faster.

ThermoSyphon® system, the latest extension of the legendary patented 3D Bionic Sphere® system has been newly integrated on the back and the side of the chest. Its complex 3D structure of inner and outer air channels 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 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.
