The Cooling Vest is help prevent workers from overheating. The most frequently used Cooling Vests work either through evaporative cooling or phase change.

Evaporative Cooling Vests. The evaporative cooling vest works the same way that sweat does, without the smelly side effects. Evaporative cooling vests are extremely absorbent. Just soak in cold water, and in a couple of minutes cooling polymers or cooling crystals in the vest absorb water and are able to hold it for hours. As the water evaporates it takes heat with it, keeping the wearer cool.

Cooling Vests aren’t just for keeping wearers from overheating either. Ergodyne is just one of many manufacturers that produces hi vis safety vests with cooling properties. These are perfect for road workers and others who need to stay cool and be seen.
