Hi all, I have to try to keep my coolest because of a medical condition, and lets face it, being hot and sticky is not all that fun--so I am always in search of "cooling secrets" and I have bought many of the new gadgets and compared them all, so here is my opinion if you want it (or not ) 1) Misty mate sport--pumps a fine mist of water on you, about the size of a 20 oz bottle of water, but a little clunky due to the weight of the pump mechanism. not too terribly bad, though. Wal Mart for 9.97 in the fan dept. I am taking it back though because I have found other things to work better. It would clip to a fanny pack, and then you can clip the hose to your shirt, and pump away at will. 2) Corabiner Misting fan by 02 Cool. 2.97 I am going back for one for everyone in the family. Wal Mart 2.97 in the fan dept on a little side display--wing stack. These are so much better than the dollar store version. Is is the size of a small squit gun, with a fan. Fits in your palm, with a key chain hook. Perfect amount of mist, plus nice fan speed. 3) IFAN by 02 Cool, Wal Mart 3.88 A fan that you can wear around your neck---a little longer tha a deck of cards. Made a horrible noise, extremely loud, not much air circulation. Taking that puppy back. 4) Water bladder Found this in the sporting goods dept, Wal mart. It has a hose attachment and you can fill it with ice and carry it in a backpack. Hubby reported it felt very good on his back. Holds up to 2 liters. 8.78 5) I have bought the neck bands that swell from wal mart too, and they have leaked and not leaked, but when they don't leak, they really kept us cool on our last trip. I bought some new ones from Miracool, as well as the "Cooling Hat"--I have not received that yet, but I'll let you know what it is like. 6) Finally, Sharper Images sells a plastic neck fan, I think it was about $30 that they say cools you significantly, but all it did was sputter water on me in the store. That was fun! Hope this helps!
