LZR Racer
The LZR Racer (pronounced as "Laser Racer") is a line of competition swimsuits manufactured by Speedo using a high-technology swimwear fabric composed of woven elastane-nylon and polyurethane. The swimsuits are available in a full-body length; they compress the body and trap air for buoyancy. The LZR Pro and LZR Elite were launched on February 13, 2008; the higher-priced LZR Elite was replaced by the LZR Elite 2 in early 2014. The LZR X was launched in early 2015. The technology is patented in Italy, and protected worldwide.
In its ruling in 2008, FINA deemed the LZR Racer swimsuits provide an unfair advantage to the wearer, leading to a ban on all swimsuits of a similar nature.
