Outstanding performance whatever the conditions. What sounds like an advertising slogan was the development target: an all-purpose product, which is able to transmute. In the burning heat of the sun the anatomically shaped jacket can be transformed into a vest and the sleeves can be stowed in a back pocket. Its material xitanit™ is able to reflect radiated heat just like the fur of the desert fox Fennek. If bad weather, wind and rain threaten the runner, the bionic membrane symbionic™ provides perfect protection. Both variants guarantee a perfect climate management by means of the patented 3D-BionicSphere® System on the back.
