I had designed a system to cool down the body for mental health support. It is always nice to see how such system can be used in another context such as the Nike Lab that designs innovative garments for athletes. One of the product, that I found in the Print edition of Fast Company Magazine, is a jacket that cools down the body. Discovering that performance falls off drastically when core body temperature hits 103 degrees, the Nike lab designed a vest that slows the rise of core body temperature. It is simply filled in with water, then frozen overnight. The vest is meant to be wear an hour prior to competition.
