The Chilly Pad provides an innovative way to cool down while enduring outdoor heat and/or high levels of physical activity. Perfect for anyone engaged in sports or work, 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 (about 1-4 hours, depending on conditions), you simply re-wet the towel in hot or cold water and wring it out. Within minutes, it's cool again. It's also machine washable, and comes in its own storage container for years of reliable use. Handy size: 27" x 17"
