The Chill-Its Economy Evaporative Cooling Towel is made with the same super-evaporative PVA material as our other Chill-Its cooling towels but is now 20% 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 re-wet to activate. Perfect for anyone working in the head and exposed to possible heat related illnesses, this evaporative towel is the perfect cooling headwear. Great for workers in construction, carpentry, mining, landscaping, OR for outdoor activities like camping, yoga, baseball, softball, soccer, running, biking, days at the beach or on a boat, golf, yard work, fishing, gardening, hiking, riding motorcycles and more, this cooling towel is a no brainer!
