Cooling vests

I was searching on the net and found what seemed to be a decent cooling vest for only $25.99. Soak it for a few min, it will keep you cool for at least 5-10 hours. I've seen this same vest on other sites, but this was the cheapest. The link is http://www.palmflex.com
Of course there are better ones out there, but this is inexpensive and will get the job done, especially in this triple digit weather...
