LZR Racer
In February 2008, Speedo launched the LZR Racer swimsuit based on woven elastane-nylon and polyurethane (50%). The suit was developed by Italian company Mectex, in association with the Australian Institute of Sport and NASA, which provided wind tunnel testing facilities. The suits were manufactured at Petratex, a textile factory in Paços de Ferreira, Portugal, where the technology is patented. Like other suits used for high competition racing, LZR Racer allows for better oxygen flow to the muscles, and holds the body in a more hydrodynamic position, while repelling water and increasing flexibility. The seams of the suit are ultrasonically welded to further reduce drag. The suit is 100% chlorine resistant and quick in drying.
