The LZR Racer is a swimsuit by Speedo, the world’s leading swimwear manufacturer. It was introduced in February 2008 after a grueling design collaboration between Comme des Garçons, the Australian Institute of Sport, and the wind tunnel testing facilities of NASA.
Composed of polyurethane and spandex, and developed with the help of fluid analysis software, the suit gained notice during the 2008 Summer Olympics when it was worn by champion swimmer Michael Phelps. It’s not without its downsides, such as the 20 minutes that it can sometimes take to put it on. That’s a small price to pay, though, to get the performance benefits it brings.
