More power without performance slumps caused by overheating? Get more with the X-BIONIC® THE TRICK® 4.0 RUNNING SHIRT LONG SLEEVE MEN. The new 4.0 generation is the first to feature the Retina® ultra-high definition quality for maximum accuracy of functionality.
The patented THE TRICK® system is unique: it tricks your brain in order to save your warm-up time and to improve your performance. How? THE TRICK® creates heat zones along the spine in order to activate heat sensors. These sensors signal "heat" to the brain, which then triggers an early onset of sweating. The result: evaporative cooling is activated before you overheat. Your thermoregulation is optimized, you can perform better for longer.
Your run will be comfortable thanks to the innovative collar construction, which ensures a perfect fit. The integrated Flexor arm cuffs prevent the sleeves from slipping. Even during your first running workout, you’ll already feel the scientific edge of the legendary patented 3D Bionic Sphere® System with ThermoSyphon® technology, which is more powerful than ever. It optimizes your skin-climate management through large exchange zones on chest and back. It cools when you sweat and warms when you are cold.
