Imagine a personal cooling system that maintains a comfortable 65º F temperature. That’s the technology behind the phase change material that was developed for our Cooling Vests Cool Packs.
Until now, the only answer to heat stress was to wear an ice- or gel-cooled vest. That meant having a freezing cold pack against your body–too cold to be comfortable. To alleviate the discomfort, undergarments were needed as a barrier, defeating the very purpose of the vest. With phase change material technology, you’ll stay cool and comfortable at a temperature that feels natural to your skin and body. So comfortable, in fact, that our products can be worn directly against your skin for optimal cooling — without the fear of frostbite!
