Sweat is too precious to throw it all away; our skin needs moisture to cool itself down. When moisture evaporates from the skin an evaporative cooling process takes place that we use to maintain the optimal body temperature. Traditional technical base layers absorb moisture in its entirety so then the body steps up its sweat production. The result: Water, minerals and salts are lost. This boxer short is different. The globally unique and patented 3D-BionicSphere System leaves a light film of sweat on the skin. The body is effectively and naturally cooled as long as it"s sweating. If sweating stops, the insulation function kicks in and less energy is demanded for temperature regulation, which leaves more energy for your activity.Features:*Two-Step 3D-BionicSphere System: the high-tech knitting technology ensures optimal grip and climate comfort.*Innerlap AirConditioning Zone: woven mesh with zero insulation function allows air to circulate and aids cooling.*3D-BionicSphere System on the back: Guarantees effective ventilation so moisture is quickly wicked and transported away.*X-Impact Technology: Better performance due to graduated compression that reduces muscle oscillations, supports muscles and joints and optimises nutrient supply.
