• whether worn under a helmet or on its own
• with the X-BIONIC® HELMET CAP 4.0, you experience an unrestricted feel-good climate and optimal wearing comfort thanks to powerful technologies
• the new 4.0 generation is the first to offer Retina® Ultra-High-Definition quality for maximum functional accuracy
• the result is an ultra-dense knit in which thermoregulating functional zones are precisely positioned and can act precisely
• insulation zones prevent heat loss on the head surface, 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 flow and support temperature balance through targeted evaporation
• at the temples, the AirConditioningSpot absorbs excess moisture, allows it to evaporate outward, and prevents excessive cooling
