The Chill-Its 6602MF Evaporative Cooling Towel features microfiber cooling technology for relief in extreme heat. The soft and absorbent microfiber is lightweight and comfortable for bulk-free wear around the neck or under hard hats, and is also rated to UPF 50+ for protection against the sun's harmful UV rays. Heat-related illness continuously ranks among the top causes of worksite accidents and fatalities. Evaporative cooling technologies such as microfiber are a simple, effective and comfortable solution for heat stress prevention. Similar to how sweat cools the body, evaporative technologies use an external water source to draw heat away—helping to regulate body temperature while providing cool relief. When activated, this cooling towel is comfortable and refreshing for even the hottest days of the year.
