Controlling sweat is good but taking advantage of it is even better. The X-Bionic Summerlight String distributes the sweat precisely where it belongs, namely, over a wide surface and directly on the skin which keeps the body's cooling system optimised. The runners need less energy for temperature regulation, and therefore performance ability and potential increases. If there is no sweat being produced, the action changes. Insulating air is stored and the systems serves to warm. Lighter than its big brother, the X-Bionic Energizer™, it still offers the same technology: Cools when you sweat, and warms when you freeze.


  • 3D-BionicSphere® System at the tailbone - The sweat of the lower back area is conducted through the 3D-BionicSphere® System to the tailbone for evaporation. The SweatTraps® on the lower back are targeted specifically at catching sweat flowing toward the buttocks. This first phase, which often leads to friction sores, is interrupted before it can even begin.
  • Skin NODOR® Nano Technology - Skin NODOR®‘s pH neutral ions actively inhibit bacteria build-up and minimize odour-causing microorganisms.   
  • Sweat Traps® at the lower abdomen - Trap perspiration before you start to feel it. Wick perspiration 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 Guides® - Work like spacers and borders along the Air-Conditioning Channel® for effective air circulation.
