No matter what sport you play: If you are cold in the sensitive area of the head or sweat during intense activity, the X-BIONIC HEADBAND 4.0 takes over the effective temperature and moisture management. The new 4.0 generation is the first to feature the Retina ultra-high definition quality for maximum precision of functionality. The result is an ultra-dense knitted fabric in which thermoregulating functional zones are precisely integrated.

The high-performance thermoregulation of the legendary, patented 3D Bionic Sphere System on the forehead ensures a constant feel-good climate. It cools when you sweat and warms when you are cold.

Sweat Traps catch the sweat before it begins to flow and support the temperature balance through targeted evaporation. The Highly Elastic Band adapts to any head shape and guarantees optimal wearing comfort.

  • NEW 3D BIONIC SPHERE SYSTEM. The patented, award-winning 3D Bionic Sphere System stops unpleasant moisture, the feeling of overheating and the risk of cooldown during rest and recovery phases.


  • ONLY WITH X-BIONIC 4.0: INNOVATIVE RETINA ULTRA-HIGH-DEFINITION TECHNOLOGY. Provides ultra-high definition texture, ultra-high density function transmission and ultra-high precision body zoning.


  • SWEAT TRAPS Ergonomically positioned sweat traps prevent the moisture from dripping and provide active cooling. Patented in 22 countries.
