Wickers Sportswear is a seller of the finest performance sports and thermal underwear available in the outdoor market. Skiers, hikers, campers, snowboarders, runners, or anyone who works outdoors will find Wickers appealing. Wickers manufactures and distributes performance sports and thermal underwear through almost all the major outdoor retailers, including Wickers Europe, REI, L.L. Bean, and Cabela's. The product, Akwatek, actually duplicates and enhances the thermoregulatory actions of the body. It is unlike other capillary action fabrics that need to be worn close to the skin to transport moisture. In fact, Akwatek not only pulls moisture away from the body much faster than capillary action fabrics, it also creates a vapor barrier in cold temperatures. Further test results show that Akwatek continues and improves evaporation of water even after repeated washings. Akwatek keeps the wearer cool in warm temperatures, and warm in cold temperatures, making it the only multi-seasonal performance underwear.
