Whether you wear caps under your helmet or on their own, with the X-BIONIC® HELMET CAP 4.0 you will experience unlimited climate comfort and optimal wearing comfort thanks to high-performance technologies. The new 4.0 generation is the first to feature high-quality Retina® with maximum functionality - resulting in an ultra-fine knit fabric where thermoregulatory functional zones are precisely positioned.



Insulation zones prevent heat loss through the crown of the head, and the legendary patented 3D Bionic Sphere® System enables adaptive thermoregulation by cooling when you sweat and warming when you are cold.



Sweat Traps® capture sweat before it starts to run down and support temperature balance through targeted evaporation. On the temples, the Air Conditioning Spot absorbs excess moisture, allowing it to evaporate outwards while preventing excessive cooling.

You can use X-BIONIC clothing for cycling, running, fitness, hiking, skiing or as a basic functional layer for any movement.
