The X-Bionic Headband 4.0 features an ultra-high-definition Retina construction of functional zones that are positioned with millimetre precision. Legendary, patented 3D Bionic Sphere system enables adaptive thermoregulation by cooling when sweating and warming when cold. Sweat Traps trap sweat before it begins to flow and support temperature balance through selective evaporation. At the temples, the Air Conditioning Zone absorbs excess moisture and allows it to evaporate to the outside.

Technologies:
- Retina
Retina provides optimised function signalling and efficiency for better cooling and support. As with the millions of sensors in the human retina, more information from the skin can be processed. Leading to unprecedented results.

- 3D Bionic Sphere
The 3D Bionic Sphere system leaves a thin film of moisture on the skin without the body sensing the moisture. The Sweat Traps system transports excess sweat, allowing it to evaporate and removing it through thermal dynamics. What remains is just a comfortable, thin, cooling layer of moisture. Evaporation occurs in 3 ways, activated by body heat: On the skin, to cool. On the SweatTraps, to process excess moisture. In the Evaporation Surface Expander, where the excess is finally evaporated. Whether it's extremely cold or unbearably hot, you'll always have a perfect performance climate. Refreshes when you sweat. Evaporation across a large surface area to process excess moisture. Excess moisture is continuously replaced by the subsequent flow of fresh air. Transfers excess moisture.
