ABSTRACT:
A micro-climate cooling vest of lightweight material of double wall construction, the body-proximate portion of which is comfortable and compatible with the clothing or skin of the wearer contains an internal liner portion comprised of a sealable insulative pocket that contains a heat transfer material that changes phase from solid to liquid within a practical range (e.g. 60.degree.-90.degree. F.) of desired body temperature cooling action, and operates to draw body heat away from the wearer in the course of its phase change form solid to liquid state. To augment the cooling action of the vest, an additional layer of ice may be used in conjunction with the primary phase change material, with the primary phase change material acting as a thermal diode.
