Recent findings by Professor Winfried Joch of the Institute for Sports Science at the Münster University and Dr. Sandra Ückert of Dortmund University show that endurance athletes use up to 97% of their energy on regulating their body temperature. This means: keeping cool improves performance. Sweating is mankind's own natural and effective system for cooling down. The X-Bionic Running Speed Shirt uses every drop of your sweat to cool you down by leaving a thin film of sweat on the skin in the active phase, as nature intended, which provides a cooling effect during evaporation. Excess sweat is processed and evaporated by the 3D-BionicSphere-System.

But then, when you finish your run, the warm air in the InnerAirChannels form an insulation barrier against the cooler ambient air surrounding you, thus keeping you warm as you cool down after the run. In addition to being a highly technical garment, designed specifically with your performance in mind, the Speed Shirt is made from soft-touch fabrics, so is exceptionally comfortable too.
