Portable personal cooling technology developed for NASA. Adapted by Cool Shirt® for the most extreme conditions on Earth.

Don’t let HEAT STRESS take anyone out of the action. Utilizing NASA study guidelines, Cool Shirt® temperature controlled cooling systems utilize ice and water circulated through a variety of cooling garments, including heavy-duty lightweight T-Shirts and reusable vests. COOL SHIRT® Systems reduce heat stress, heat fatigue, cramping, and exhaustion —while increasing alertness and safety, improving morale and productivity, and reducing heat related illnesses. Users have told us that the longer time between rehab or cool-down breaks—and subsequent increase in worker efficiency and productivity—makes a Cool Shirt Pay for itself, with surprising speed.
