ThermApparel

ThermApparel is a private U.S. company that designs and sells wearable cooling products intended to help people manage heat sensitivity and maintain activity in daily life, work, exercise, and recreation. Its products use reusable bio-based phase change material cooling packs integrated into lightweight garments and accessories, with flagship products including the UnderCool 3, UltraCool, RallyWrap, CoolSleeve, and Headband. The company originated from work at Rochester Institute of Technology and initially focused on people with multiple sclerosis and other conditions associated with temperature intolerance, while also marketing products for broader consumer and occupational heat-relief use. ThermApparel appears to operate as a commercial-stage manufacturer and direct-to-consumer e-commerce business rather than a drug-development biotech or pharmaceutical company.
