...and works great. I've been using one for five seasons, if not longer. Makes unbearable summer heat so much easier to handle. It does work on the same principle as a wet towel, but it is much smaller and convenient to use if you wear regular (not athletic) clothing. Water doesn't drip on your shirt, as it does from a towel, and the bandana stays wet for a long time. I usually try to wet it whenever opportunity presents itself, preferably with chilled water, and air dry when not wearing it.
