The X-BIONICยฎ BONDEAR CAP 4.0 cap guarantees you perfect thermoregulation thanks to innovative technologies.
The new generation 4.0 is the first to have the Retinaยฎ technology for a further improved positioning of functional zones.
The insulation zones prevent heat loss through the top of the head and the patented 3D Bionic Sphereยฎ system allows thermoregulation by cooling you down when you sweat and warming you when you are cold.
Sweat Trapsยฎ capture sweat before it starts to slip over the skin. On the temples, the AirConditioningSpot absorbs excess moisture, allowing it to evaporate outside while avoiding overcooling.
