MiraCool® provides all-day cool comfort on hot days
Vest helps keep you cool, plus is highly visible to keep you safe
MiraCool® products contain highly absorbent crystals that absorb 1,000 times their weight in cool, refreshing water. Once soaked or saturated, they use the power of evaporation to provide extended cooling. Designed to be worn against the head, neck or body for maximum effectiveness; reusable and hand washable. Crystals are encased in cotton for all-day comfort. Airflow and the natural evaporation of water keep you cooler and more comfortable. When worn over a T-shirt or under personal protective garments, it reduces the chance of heat stress. Submerging in cool water for 30 minutes daily activates the gel crystals. Side buckles are adjustable for a custom fit. Hi-visibility orange. Imported. One size fits up to Mens 46" chest size.
