Optimize your energy management while running with the innovative X-BIONIC EFFEKTOR G2 RUN SHORTS MEN with Ideo-Waistband, the running shorts of the new X-BIONIC 4.0 generation for the innovative sporty man. The energy released by the earlier onset of evaporative cooling flows directly into your running performance. Even during your first running workout wearing these men’s shorts, you’ll immediately feel the technological advantage of the ThermoSyphon system, the next generation of the legendary patented 3D Bionic Sphere system. The integrated X-BIONIC Partialkompression exerts gentle pressure on the skin via bars. This protects you from premature muscle fatigue and simultaneously maintains the important cooling effect of perspiration. Iso-pads above the hip bone protect the underlying organs from cold by providing accurately targeted insulation. Interaction between the Innerlap Air conditioning Zone (a special cooling surface on the inside of the thighs) and the Sweat Traps supports your performance with optimized moisture transport and cooling effect. 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.
