If it’s hot and raining near you, our Cool Pack Vests are the right way to cool you down. The Cool Packs stay at a constant 58 degrees for up to 2.5 hours. They do not require any air flow to operate and can be used under any clothing. The vest weighs 6 pounds and is 1.5 inch thick. Our Cool Packs are used under military combat gear and hazardous materials suits.
Phase Change Method
Just place the Cool Pack insert (not the vest) in freezer or ice water for up to 45 minutes until it is solid. Then place the Cool Pack in the vest. Your Cool Pack Vest is now ready to use.
