During the summer months, the 10 to 15 minutes that it takes to run a heat or feature race can be almost unbearable, if not dangerous. A pocket on each panel is there to hold a reusable, foil cool pack. Right before a race, place a cool pack in each pocket, zip up, and go racing. After the race, pull out the cool packs and throw them in the ice chest and they’ll be ready for the next race. It’s suggested that two or three sets of cool packs be purchased. This allows them to be rotated to maximize the amount of time spent in the cooler being rechilled
