WARMS WHEN YOU'RE COLD. COOLS WHEN YOU SWEAT. The cooling effect of X-BIONIC® Underwear is only activated once you start sweating. Its clever regulation system works with the most reliable of starters: your sweat. One-of-a-kind and effective, with its cooling power always exactly when you need it. 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. Your body is sounding the alarm: Warning, threat of overcooling! X-BIONIC® Underwear prevents these chills. If no sweat is present, then a unique process uses air heated by the body asthermal insulation.

*blemished. the fabric on these shirts has yellowed in several areas. it could be that a bit of bleach will wash it out. if not, well you're saving a whole bunch of money on a base shirt that'll spend most of its life covered by outer layers. please see the photos for examples.


  • ISO-Shoulder - The wavelike structure of the ISO-Shoulder™ lies over the shoulders, keeping the body warm and guarding against chills.
  • 3D-BionicSphere System in the chest area - Without giving the body the impression that it is getting cold, fresh air from the 3D-BionicSphere® System in the chest area cools down the body temperature. The air is tempered inside the ducts, working like a sluice. Hot, moist air is disposed of using the dynamics of body warmth and then replaced with new fresh air.
  • AirConditioning Channel - The AirConditioning 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 - Guarantees effective ventilation so moisture is quickly wicked and transported away. No sweat means insulating air pockets in the wavelike structure protect against cold.
  • 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.
  • 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.
  • X-Impact Technology - Better performance due to graduated compression that reduces muscle oscillations, supports muscles and joints and optimises nutrient supply.
