cool neck ties for the heat?

Sue or anyone –

Have you ever tried one of those “cool neck ties” with the polymer crystals in them for helping with the heat? My family has used them in the desert and when camping for years, and they are pretty amazing in how much they help keep you cooler.

In the last few years there are tons of places that either sell them online, or that offer instructions for how to make them, as many people make them and send them to troops in Iraq. A google search of “cool neck ties” should bring quite a few good results for more info about them.

The only problem I’ve had with them is when I’m in a humid area, you have to make sure you don’t store them in a plastic bag or anything like that, or they’ll mold instead of drying out between uses.
