Nike To Cool Off Olympic Competitors
Could it be that Nike is looking to the ‘fridge for innovation? To be introduced for the Beijing Olympics, their PreCool vest helps lower the body's core temperature, conserving energy by keeping the body from attempting to keep cool itself. Constructed with triangular cavities of differing sizes, the vest is filled with water, then frozen before wearing. It's claimed that when worn for one hour before competing, the athlete lasts 21% longer than without the vest.
