Compression running apparel gets a boost of muscle specific support with CW-X compression run tights, shorts, socks and calf sleeves. Wacoal Sports Science dedicates CW-X Compression to people all over the world who love the exhilaration and challenge of sport. Japan's Wacoal Corp., the world's largest manufacturer of intimate apparel, has spent half a century creating clothing born of a deep understanding of the body. For forty years, scientists at Wacoal Human Science Research Center in Kyoto, Japan have studied kinesiology, the science of human movement. They have tested over 35,000 people and analyzed injuries relative to warm-up and cool-down periods. They have come to understand the mechanics of joints and muscles in minute detail. This exhaustive study of body movement has culminated in over 15 U.S. patents and CW-X Conditioning Wear. Combining its scientific knowledge of the human anatomy with its experience in complex fabrication and apparel design, the company first entered the performance sports apparel market in Japan in 1991 with CW-X Performance Conditioning Wear. Recently the company launched the CW-X brand in the US market through the newly formed Wacoal Sports Science Corp. New ideas, science to back those ideas and a commitment to athletic performance and injury prevention is the reason has decided to offer CW-X to our loyal customers.
