Details

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.
