Integral cooling garment for protection against heat stress

Claim 1

An integral cooling garment for the protection of a person's body from ambient heat, comprising: an outer lining, a permeable inner lining, and a plurality of gas-conductivity tubes therebetween; each lining including a first layer of insulating material; a container for containing fluidized carbon dioxide and comprising a pressure reducing valve; said tubes having a nozzle detachably connected to the valve for delivering liquified carbon dioxide to the tubes where the liquified carbon dioxide converts to solid carbon dioxide and where it then sublimates to carbon dioxide gas; the tubes also being microporous of a predetermined pore size for releasing carbon dioxide gas into the areas between the inner and outer linings and through the inner lining into contact with a person's body, whereby the article of clothing is useful without continuous connection to the container during sublimation of the solid carbon dioxide.
