One of the “coolest” items that I stumbled upon this morning was the Frogg Toggs “Chilly Pad,” a 33″ X 13″ light towel that turns cold with the only the application of water. You pick this thing up and and it honest to goodness feels like it has just come out of a refrigerator — except that that it has not been near ice or refrigeration of any kind. The secret is in the fabric weave, which evaporates water at such a high rate that the temperature of the material drops rapidly as soon as it is wet. And it stays cool as long as it doesn’t dry out. If you are planning a trip to the tropics this year, you might want to take a look at these. They’re $14.99 but on sale for the next month at half that price.
