High-technology swimwear is designed to reduce drag and improve swimming performance. Speedo claims that their LZR Racer reduced drag or water resistance by 38% compared to a traditional Lycra practice swim suit. This high-technology swimwear is designed to minimize drag while maximizing support to muscles. Some companies claim that their fabrics reduce drag even more than the water's normal friction against the skin. To do this, they design high-end lines of competitive swimwear that cover the arms and legs. The fabric used for high-technology swimwear is light and water-repellent. The material is often composed of highly stretchy spandex and nylon. High-technology swimwear is often made using bonded seams, to reduce further drag. These suits also provide the compression necessary to increase performance.
