Chill-Its 6604 Multi-Purpose Cooling Towel combines super-evaporative PVA (polyvinyl alcohol) around the neck with ultra-soft microfiber ends, providing a unique, two-in-one solution to keep workers cool and clean in the heat. PVA absorbs and retains water for consistent cooling around your neck. Microfiber ends work great for wiping or refreshing your hands, face and glasses. Evaporative cooling technology is a simple, effective and comfortable solution for heat stress prevention. When activated with an external water source, this towel helps regulate body temperature. PVA dries stiff. Simply rewet to reactivate cooling technology that lasts up to 3 hours. Convenient size is perfect for on-the-go use and low-bulk wear. Hang tag allows easy drying and storage. Machine-wash and air-dry for reuse.
