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 new hyper-evaporative material that retains water while remaining dry to the touch. When wet, the towel becomes considerably cooler that the outside air, thereby providing cooling relief to the user. When it stops cooling (between 1-4 hours depending on conditions), you simply re-wet the towel in hot or cold water and wring it out. Within minutes it is cool again. It is also machine washable.
