Application

The PCM cooling vest is engineered for high-temperature workplaces, extended outdoor activity, and professional users working in demanding heat environments. Using advanced phase change materials (PCM) embedded inside the vest, it absorbs excess body heat as temperature rises, providing gentle thermal buffering without the icy shock or rapid temperature drop typical of ice packs. It requires no power and no activation mechanism, delivering stable, long-lasting temperature control that helps maintain core body temperature, reduce heat stress, and support safer, more comfortable, and more sustained physical output and work performance. PCM cooling vest inserts — designed to replace or expand the phase change modules inside the cooling vest, providing a more flexible, economical, and scalable wearable cooling solution.

The PCM cooling helmet liner works with standard helmets and uses phase change materials to absorb excess heat within the limited head space, delivering steady, comfortable cooling. Compared with traditional helmets that easily trap heat, this solution significantly improves comfort and mental clarity, making it ideal for electrical maintenance, firefighting, military and police use, cycling, construction, and other applications requiring enhanced head heat management.
