I came across this towel that gets cool at the store the other day. There was one on the counter to try and I was quite impressed with how cool it got. All it uses is water and a few good shakes and it is pretty cold. I use it on my feet when they start to flare. It helps quite a bit with the pain. The website is: www.chillskinz.com The towel stays cold for hours. I purchased the large one.
I saw one of these at Bed, Bath & Beyond and was considering buying one... Maybe I will go back and pick one up!
Thanks!
