Especially something that will help me with cooling off in the heat.

Stumbled across a sports towel called Chilly Pad by Frogg Toggs.
Forgot my cooling scarf yesterday when we went out for some errands. Before we left one of the stores to spend some time outside, found this on our way to the check out. It almost reminds me of one of those chamoise towels hubby uses on his car to dry it off, LOL.
Basically, just soak it in cold water, squeeze the excess water out, and go. Had it on my neck outside for about an hour yesterday, and it worked surprisingly well. Just run it under cold water again to recharge it.
Anyone else find some neat ways to keep cool this year?
