"Wind-tunnel testing at NASA’s Langley Research Center played a key role in the development of Speedo’s LZR Racer swimsuit, proving which materials and seams best reduced drag as a swimmer cuts through the water. The swimsuit made a splash during its Olympic debut in 2008, as nearly every medal winner and world-record breaker wore the suit. Full-body swimsuits, such as the original LZR Racer, have since been disallowed from international competitions, but a modified version of the suit continues to be popular among professional competitors." -NASA
