Nano-fiber Swimsuits

Swimmers at this summer's Olympic games will undoubtedly be wearing the latest in fiber technology to gain a competitive edge - like the Aquaforce Infinity swimsuit, which is made of two different nylon materials (front and back) to minimize drag in the water. The traditional rubber or silicon in the hems has also been replaced with a proprietary "nano tape" to prevent slippage without inhibiting blood flow.

The tape consists of ultrathin fibers that are 7,500 times finer than a strand of hair. Bundled together, they form a rough surface with three times the friction force of polyester.
