Looking for a “cool” edge over your fellow athletes? (please forgive the pun.. I just couldn’t help myself there) Check out the Nike PreCool vest which aims to lower your body’s core temperature. The idea is as follows: Lower your core temperature before you work out and your body will perform more efficiently during the workout because it doesn’t need to focus on cooling you down. If used up to an hour before a workout or competition, an athlete can supposedly last 21 percent longer than without it. The vest has an inner layer filled with frozen water which is then enclosed with aluminum on the outer layer. Interesting stuff.. though I don’t know if I would be willing to use this for my workouts.
