The bike jacket is aerodynamic, very flexible due to knitted inserts on the back and thanks to the symbionic™ membrane windproof and breathable. Highly innovative is the ClimateSpeed-Spoiler: due to its tear-off-edge the wind stream is transformed into turbulent flows. This leads to less wind resistance and more speed. In the inside of the jacket the 3D-BionicSphere® system uses sweat to cool. Further it encloses warm air to isolate the athlete against cold.
