LESS WEIGHT, MORE ENERGY. Controlling sweat is good. Taking advantage of it is even better. The Energizer Summerlight distributes the sweat precisely where it belongs - namely, over a wide surface and directly on the skin. The body"s cooling is optimised, the athlete needs less energy for temperature regulation, and performance ability 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 Bionic Energizer, it still offers the same technology: Cools when you sweat, and warms when you freeze. 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. 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. 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. X-Impact Technology Better performance due to graduated compression that reduces muscle oscillations, supports muscles and joints and optimises nutrient supply.
