Frogg Toggs Chilly Pad Cooling Towel. If the weather is hot, a Chilly Pad Cooling Towel is the answer! It's ideal for any hot, strenuous activity, from team sports and lawn care to a killer workout in the gym. Just keep it nearby for a quick cool down. The Chilly Pad Cooling Towel is made from a hyper-evaporative material that retains water while remaining dry to the touch. When wet, these cooling towels begin to evaporate and cool, providing cool, soft comfort to the user. When it stops cooling, simply re-wet it in hot or cold water and wring it out, within minutes, it's cool again.The Chilly Pad material is highly absorbent, (like a sponge) and can absorb up to 8 times its weight in water. Once wet, the towel produces a cooling affect with the help of simple evaporation. As long as the towel is wet, exposed to the air, and allowed to "breath"... the Chilly Pad will evaporate... and cool.
