The energy released by the earliest start of evaporative cooling directly influences your running performance. You will immediately feel the technological advantage of the ThermoSyphon® system, the next generation of the legendary and patented 3D Bionic Sphere® system. Partialkompression® exerts gentle pressure on the skin through its special framework. This protects you from premature muscle fatigue while maintaining the cooling effect of perspiration. The interaction between the Innerlap Air conditioning Zone and the Sweat Traps improves moisture transport and the cooling effect. Manufactured using ultra-high resolution Retina® technology.
