Have you seen these? http://www.chilltowels.com/about.htm One of the pros at Grandfather Mountain, I think it was Mike Pockoski, had a bunch of these giving them out, because Chill Cooling Towels are one of his sponsors. He swears by them, gave KO one, and he was amazed by how cool it was. Supposedly all-natural, too. They also had a booth at the games. Just thought you may want to check them out.
