ABSTRACT A heat-intercepting shield or shroud in the form of a garment, blanket or belt having on at least one surface thereof one or more pockets to receive replaceable packets of refreezable material which absorb large quantities of heat as the material melts. Each pocket has two coextensive fabric layers stitched together to form opposite pocket walls. Over the entire pocket area and next to one wall are coextensive layers of reflective material and of insulating material. These materials are flexible and one or both are stitched next to that one pocket wall in seams at the edge of the pocket so that both heat reflection and retardation of heat flow by the insulation occurs over the entire pocket area. Between the layers of insulation and reflective materials and the other pocket wall is a space for a heat absorbing packet or packets of frozen gel. The side of the shield or shroud with the packet or packets is placed toward the object to be cooled or protected from external radiant, conductive or convective heat. The garment or blanket of this invention achieves practical protection for a worker in unusually hot environmental conditions and is very durable, low cost, easily laundered, comfortable to wear, and provides a very convenient way to replace refreezable heat absorbing packets therein under working conditions.
