The VENT CAP cap protects you from the sun and keeps your head cool at the same time.Jack Wolfskins TEXADRI absorbs sweat, dries quickly again and is highly breathable. Mesh inserts provide additional ventilation.MICROBAN technology permanently reduces the formation of unpleasant odors. So you always stay fresh and also have to wash the cap less often. TEXADRIJack Wolfskin's fiber technology for active moisture management. TEXADRI materials quickly absorb sweat, wicking it away from the skin and distributing it over a large area to effectively accelerate evaporation. This allows moisture to be better absorbed and transported and the fabric dries faster, so that as little moisture as possible forms on the skin. The basis for this highly breathable fabric are materials that store very little moisture due to their fibers and quickly release it to the next layer or the ambient air due to their fiber structure.
