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.
A device for controlling the transfer of heat with respect to a body comprising heat exchange material that changes between solid and liquid phases at its melting/freezing temperature, and means for supporting said heat exchange material in thermal communication with the skin of the body in both its solid and liquid phases and thereby causing the temperature of said heat exchange material in each of its phases to be applied to the skin of the body, and wherein the melting/freezing temperature of said heat exchange material lies in a temperature range on the order of 60.degree.-90.degree. F., so as to be comfortable during prolonged thermal communication with the skin.
