The CW-X Story

Wacoal Sports Science dedicates CW-X® to people everywhere in the world who love the exhilaration and challenge of sports. Because to celebrate sports is to celebrate what's best in human beings.

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. Combining its scientific knowledge of the human anatomy with its experience in complex fabrications 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.

Wacoal Sports Science Corporation, headquartered in New York City, is a wholly-owned subsidiary of Wacoal International. The company's mission is to meet the sports performance needs of the active US consumer through the CW-X brand, the world's first truly anatomically-engineered high performance sports apparel.

In a study in Kyoto, Japan, electrical pulse activity of the muscles (muscles firing into motion) was measured electromyographically. Unsupported and partly supported legs both show frequency decrease during exercise, indications of fatigue. Legs supported by CW-X® showed negligible frequency decrease. In a study in Montpelier, France, differences in fatigue in runners wearing shorts, regular spandex tights, and CW-X® Conditioning tights were measured comparing VO2 oxygen uptake levels over 15 minutes of running at 80% of maximal effort. When wearing CW-X® tights the results showed 26% and 36% lower oxygen usage compared to regular tights and shorts respectively, indicating lower energy expenditure in CW-X® tights.
