Year Introduced: 2008
Sport: Swimming

Composed of spandex, nylon and polyurethane, the LZR Racers were the high-performance, form-fitting bodysuits that nearly swept the Beijing Olympics in 2008. That's not an exaggeration either: 98 percent of the swimmers who medalled that year were wearing an LZR suit, and after only one year in competition, it had already helped break 97 world records. However, it would soon go on to be deemed an unfair, technological advantage, and FINA, swimming's governing body, ruled in July of 2009 that the suits could no longer be used in competition. We'll never forget this momentthough. RIP LZR.
