The Chill-Its Gray Evaporative Cooling Towel features advanced PVA cooling technology for relief in extreme heat. When wet, this towel remains lightweight and comfortable for bulk-free wear around the neck or head. Heat-related illness continuously ranks among the top causes of worksite accidents and fatalities. Evaporative cooling technologies such as PVA (poly vinyl alcohol) 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 PVA cooling towel is comfortable and refreshing for even the hottest days of the year. The PVA material will dry stiff like a sponge-simply rewet until soft to reactivate. Machine wash, hang dry and conveniently store this cooling towel in the included plastic container when not in use. This evaporative cooling towel is ideal for construction, landscaping, roofing or anyone working in the heat. It can also be used to reduce the risk of heat stress for outdoor recreational activities.
