Somebody already mentioned wetting a t-shirt, I do this straight out of my water bottle on job sites (construction laborer, yes, outside in the heat all day long), not only does it do just as good as a mist bottle, but it's one less gadget to carry (or lose or forget), and it's money that can be spent elsewhere. While I'm at it, in the worst of the Summer heat, I sleep without A.C. for the reason already mentioned, it makes the days out in the heat tolerable (sp?). Don't be afraid to SWEAT, and drink PLENTY of water and/or gatorade, the bottles would be hard to send, but they make powdered mix you could send in a care package. Most "NEW" or "AMAZING" gimicks aren't either one.
