Regulates your personal micro-climate, developed by scientists, proven by endurance athletes. You know that unpleasent feeling of being sweaty, then breaking out in goose bumps.

  • SweatTraps®

    Trap perspiration before you start to feel it. Sweat is wicked away so it can evaporate using heat dynamics. A film of perspiration - too thin to be noticeable - is left behind to cool the skin.

  • Air-Conditioning Channel®

    The Air-Conditioning Channel® is a ventilation system of channels that flow around the body, continuously carrying away moisture and warmth. It allows air to flow to body regions not normally accessible by fresh air circulation.

  • 3D-BionicSphere® System on the back

  • ExpansionRibs™

    The knitted fabric of the ExpansionRibs™ folds apart based on the accordion principle, insuring that cold doesn‘t cool down the elbows. Even when sharply bent, the insulating effect is maintained through warm air stored in the interior. The flexibility of the ExpansionRibs™ and the elasticity of the yarn allow a frictionless freedom of movement.
