ABSTRACT:
A cooling jacket provides personal cooling for the wearer by convection as cold carbon dioxide gas circulates within the space between the inside surface of the jacket and the wearer's body. Dry ice is held in pockets inside the jacket, aand each pocket is vented to permit the gas to diffuse through the pocket into the space. The bottom of the jacket is provided with a waist band which closes the space at the bottom and restrains the escape of the relatively heavy carbon dioxide gas.
