ABSTRACT:
The invention relates to a cooling garment, preferably in the form of a vest that contains pouches containing a phase change material. The pouches cover less than the surface area of the vest to thereby permit evaporative cooling to occur and to contribute to the overall comfort of the wearer. An alternate embodiment includes a honeycomb structure which is contained within the pouches and which contains a macroencapsulated phase change material and allows the escape of perspiration through the garment. A heat transfer fluid is adapted to circulate throughout the pouches. The honeycomb structure is designed so that the macroencapsulated phase change material remains within designated ones of the honeycombs, but that permits the flow of the heat transfer fluid through the pouch.
