Nike has unveiled the PreCool Vest, developed specially for the Bejing 2008 Olympics. The vest promises improved performance by cooling the athletes' muscles before they compete. Studies show that muscles perform better when they're not wasting their resources on cooling down.

The PreCool Vest, which is to be used one hour before competitions start, features multiple triangular cavities filled with frozen water. The vest lowers the body temperature, allowing the athlete to last 21% longer.
