State of the art sport shirt from X-Bionic. Athletes use a large part of their energy to control the body temperature. The Fennec Running Shirt helps the body in this. This means more performance. Inspired by the desert fox, or Fennec, whose shiny silver fur reflects heat from the sun and the surroundings to allow it to survive in the hot desert, the Fennec Running Shirt integrates the revolutionary material xitanit™ which is also able to reflect radiated heat and works like a heat shield. The Fennec® shirt is hot on the outside and stays cool on the inside. Dispersing of heat, the distribution and evaporation of sweat, as well as the Heatpipe® Construction are additional cooling technologies in the Fennec® Running Shirt.
