The cooling suit is designed as a supplemental component for various protective garment systems. The suit can be worn by fire fighters, steel mill workers, military personnel, and workers in chemical and nuclear facilities, in order to avoid heat stress and related illnesses while performing their duties. The cooling suit is worn as an undergarment beneath the existing air-tight and moisture-impermeable chemical protective garment system.
The phase change material (PCM) in the cooling suit absorbs excessive heat generated by the wearer’s body during strenuous activities. As a result, the temperature in the microclimate near the skin remains in the comfort range over an extended period of time. Regulating the microclimate temperature reduces the skin’s sweat production, which significantly enhances the wearer’s overall thermo-physiological comfort, thus substantially improving the wearer’s productivity.
