This years summer Olympics in Beijing doesn’t only cause political commotion, but it is also a commercial event. A lot of brands will use the media coverage to launch new products. This is the new Nike PreCool Vest; not your average sports equipment. The design was inspired by a 1960s mini dress and medical packaging. The triangles have a double layer, on the inside there is frozen water, the outer layer is just air for isolation. The purpose? With core cooling, athletes can often last 21% longer.
