Nasa and Speedo LZR
The LZR Racer Suit (pronounced as 'laser') is a line of high-end swimsuits manufactured by Speedo using a high-technology swimwear fabric composed of woven elastane-nylon and polyurethane. The line was launched on 13 February 2008. The technology is patented in Italy, and protected worldwide.
The suit was developed by Mectex, an Italian company, in association with the Australian Institute of Sport, with the help of Speedo's sponsored athletes. NASA's wind tunnel testing facilitiesand NASA fluid flow analysis software supported the design. The line's cosmetics were designed in collaboration with Comme des Garçons.
Like other suits used for high competition racing, it 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 suits are manufactured at Petratex, a textile factory in Paços de Ferreira, Portugal; the technology is patented in that country. The suit is also 100% chlorine resistant and quick drying. The suit includes patented Core Stabilizer and Internal Compression Panels. Speedo also partnered with ANSYS, one of the world's leading engineering simulation software providers, in creating this suit.
Endorsed for competitive use by FINA prior to the Beijing Olympics, the suit reportedly can lower racing times for a competitor by 1.9 to 2.2 percent. This and other high performance body suits have since been banned from FINA competitions.
