Abstract
An article of clothing including a vest portion and a detachable hood having a polyacrylamide copolymer filler that cools the body by activating the cooling stage, which is done by placing the vest and hood in water for the required time or placing the vest and hood in ice water for required time. Top and bottom pieces of material (10), (12) will dry and the filler (14) will remain cool and moist. They are worn by placing on the body and attaching fasteners and will keep the individual cool for hours. They are made of materials that can be washed by the individual. They can be stored for days in plastic bags in the refrigerator. If long-term storage is needed, it can be accomplished by line-drying and then put away until ready for use again.
