The Chill-Its 6667 Wet Evaporative Cooling Vest is made with a lightweight PVA material that provides immediate cooling relief to the core area. The lightweight construction is designed with breathable mesh panel siding making it more comfortable than other wet evaporative vests that can be heavy to wear. A front zipper offers an easy on/off, customized fit. For best results, we recommend this body cooling vest be worn over a t-shirt and not covered by other clothing. To activate, simply run under water and wring out - no ice or refrigeration is needed. The PVA material is super evaporative and feels cooler than ambient air, keeping you feeling cool and comfortable for hours. Machine wash as needed and hang dry for longest life, the vest will stiffen as it dry's. All PVA materials dry stiff - to reactivate and soften, run underwater. Great for construction, landscaping, roofing or anybody working in the heat. It can also be used to keep cool and reduce the risk of heat stress while gardening, hiking, playing sports and more.
