This is the world's fastest swimsuit by Speedo. Speedo had come up with this specially engineered, highly flexible fabric called LZR PULSE™is ultrasonically welded so as to appear seamless. It incorporates low drag "LZR" panels designed to create a corset-like effect that supports the swimmer in the optimum body position in the water and helps them hold it for longer.
The LZR RACER’s unique design also provides swimmers with up to 5% more efficiency** in terms of their oxygen intake, enabling them to swim stronger for longer. “It makes it easier to swim faster,” said Rick Sharp, Exercise Physiologist, Iowa State University.
