The Frogg Toggs Chilly Pad Cooling Towel is a great way to cool down during hot outdoor activities like a long day fishing or even while working out. The Chilly Pad is made from a hyper-evaporative material that retains water while remaining dry to the touch. When wet, the towel begins to evaporate and cool, providing cool, soft comfort to the user. When it stops cooling, just re-wet the towel, wring it out, and within minutes, it's cool again. Measures 33" x 13".
