The Chill-Its 6601 Economy Evaporative Cooling Towel is made with the same super-evaporative PVA material as other Chill-Its cooling towels but is twenty percent thinner for lightweight cooling. This super-evaporative PVA material is designed to absorb water and create a feeling colder than ambient air temperature. This neck cooling wrap can be used for hours or for quick relief and is completely reusable; just rewet to activate. Run the PVA cooling towel under water for one minute or until saturated, wring out excess water and twirl or snap in the air for no-drip cooling. Drape the towel around neck or head for instant cooling relief. Material will dry stiff, simply rewet until soft to activate, and it's ready to go again. This evaporative towel is the perfect cooling headwear for anyone working in the heat and exposed to possible heat-related illnesses like heat cramps, heat strokes, or heat exhaustion.
