Abstract: A therapeutic cold pack is provided for temporary affixation to an area of the human body. The cold pack comprises a pair of hermetic barrier layers that are heat sealed together throughout a plurality of articulations defining a plurality of compartments. A refrigerant gel, such as ethylene glycol, is contained within the compartments and has a high specific heat such that after becoming cooled it absorbs a large quantity of heat while undergoing phase change on heating. The plurality of compartments is distributed throughout an extended area. Adjoining compartments are hinged to each other along intersecting axes. The compartments are adapted to be folded with respect to each other along the axes into a configuration that is snugly seated against an irregular three dimensional anatomical surface. A relatively large velcro-type micro-fastener area is located at the back of the cold pack.
