Query: Cool product, especially when used as a headband

After a trip to Africa, I was looking for this kind of product that could help keep me cool. The EverCool Bandanas are just what I was looking for. They soak up a lot of water and then last for a long time (after wearing it one afternoon, I put it in a sunny location and it took 2 days to lose all its moisture). Guess I now need to go back to Africa and really put them to the test.
