>> Staying cool in the heat can never be underrated.  That’s why the Imperial Instant Cooling Towel ($19.95) is worth adding to your bag.  Coolcore® provides a chemical-free cooling solution that goes beyond traditional moisture management fabrics or evaporative cooling technologies that typically rely on chemicals.  All you have to do is wet the towel, wring it out, and then wave it to start the cooling process.  Coolcore® technology results in up to 30 percent lower surface temperatures, healthier chemical-free usage, and zero degradation of the cooling effect over time or washing.  “One of our new cooling towels applied to pulse points on the body — such as head, neck or wrists — can save energy by letting your body focus on competing, not staying coo,” said David Shaffer, director of marketing at Imperial.  Imperialsports.com
