Feature CW-X exo-web support for the upper back to improve posture, balance, and arm motion for greater efficiency of movement. Can be used as an external performance layer or as an under layer for support. CW-X's Ventilator performance tops feature the company's signature Kinesio Support Web for the upper back to improve posture, balance, and arm motion. The Kinesio Support Web uses Kinesio-taping technology to create an exoskeletal support system. It specifically targets the trapezius muscles and scapular s of the upper back for improved posture and more controlled movements in the arms and shoulders. Mesh ventilation panels allow hot air to escape and cool air to enter, reducing heat igue and improving circulation. The top provides versatile performance, both as outerwear and as a base layer. Fabrics The a+ four-way stretch nanotechnology fabric yields quick-dry moisture evaporation and comfortable freedom of movement. This garment also includes a+ four-way-stretch, mesh-fabric ventilator panels. About Kinesio Support Web Technology The patented CW-X Kinesio Support Web technology mimics Kinesio taping techniques that trainers apply to injured muscles. When this technology is applied to muscles and joints, it creates an exoskeletal support system that improves biomechanics during motion. The Kinesio Support Web provides targeted support to key areas, decreasing muscle oscillation and focusing power so your muscles work more efficiently. Variable compression along the web facilitates circulation, minimizing lactic build-up and muscle soreness, so you can be active longer and recover faster. About a+ a+ is a multifunctional, lightweight, quick-dry fabric developed by Ventex. Nanotechnology has been used in the development of a+, which consists of 90 percent polyester and 10 percent spandex yarns. This combination provides a comfortable fit and freedom of movement, as well as quick-dry moisture wicking capabilities. The six-channel shape of a+ fibers results in a capillary action pulling the sweat away from the skin's surface to the exterior of the fabric. a+ yarn's wide surface area is also an intrinsic advantage over regular fibers. A wider surface area allows for greater moisture evaporation. This makes a+ one of the fastest-drying textiles available. Integrated titanium oxide fiber technology protects against ultraviolet rays, providing UPF 50+. About CW-X Gear Technology For 40 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 50 patents worldwide. Below are some further studies demonstrating the performance-enhancing qualities of CW-X Conditioning Wear. Human Science Research Center, Kyoto, Japan: Study of electrical pulse activity in muscles Muscles firing into motion were measured electromyographically for subjects wearing CW-X gear, subjects wearing competitor products, and subjects with bare legs. Electrical pulse activity decreased in unsupported and partly supported legs during exercise, indicative of igue. Legs supported by CW-X showed a negligible decrease in electrical pulse activity. Human Science Research Center, Kyoto, Japan: Study of stability, impact, and motion In this study, high-speed video analysis was used to compare stability, impact, and motion in CW-X products and regular compression gear. CW-X Support Web tights were 10 percent more stable and balanced and absorbed 12 percent more shock to the knee than regular compression tights. CW-X Support Web tops allowed 9 percent greater range of motion for the arm than regular compression tops. University of Montpelier, France: Study of VO2 oxygen uptake levels This study measured VO2 oxygen uptake levels over the course of 15 minutes of running in CW-X gear, regular compression tights, and running shorts. CW-X Support Web tights showed 26 percent less oxygen use than regular compression tights and 36 percent less oxygen use than traditional running shorts, indicating lower energy expenditure. About CW-X Japan's Wacoal Corporation, the world's largest manufacturer of 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 U.S. market through the newly formed Wacoal Sports Science Corporation. Wacoal Sports Science, 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 U.S. consumer through the CW-X brand, the world's first truly anatomically engineered high-performance sports apparel. "
