"Endurance athletes use up to 97% of their energy just regulating their body temperature" scientists have recently discovered. This means: keeping cool improves performance. With its revolutionary Fennec technology, X-Bionic has for the first time combined four different cooling technologies in a single shirt - no matter how hot it is, there's nothing to stop you running.

1. Inspired by the desert fox, whose silvery fur reflects heat, the X-Bionic Fennec running shirt uses the new and exclusive, heat-reflecting XITANIT fabric. The shiny material acts like a heat shield, getting hot on the outside but staying cool on the inside. XITANIT is an excellent conductor for dissipating excess body heat, and has also been used in X-SOCKS Speed Metal.

2. The special woven structure and the temperature-regulating 3D-BionicSphere system on the chest and back distribute sweat evenly over your body to that it can evaporate and cool you down.

3. For added cooling, the micro-active Heatpipe system draws up hot, moist air through tiny ducts, where it condenses and returns to your body. It literally uses every last drop of sweat to cool you down. Thanks to its gentle compression, the highly innovative, award-winning Fennec running shirt is extremely comfortable to wear, stimulates your muscles and assists your cardiovascular system. The perfect shirt for running in warm conditions?
