PreCool Technology
Nike has redesigned its PreCool vest - originally introduced in Athens - to make it lighter, more flexible, better fitting and refillable.
The vest, which is designed to reduce the body's core temperature, was redesigned using a grid of triangles to create a closer fit and, therefore, reduce the amount of ice (and weight) needed to cool the body.
Each triangle has two layers. The first is filled with water, which is frozen, while the outer layer insulates. An aluminium coating reflects radiant heat to help the vest stay cooler for longer.
