Abstract: A piece of clothing, such as a hat, has exterior and interior layers connected to each other only along the periphery of the hat providing unobstructed interlayer space for insertion of a thermal pack(s) for the application of heat or cold to any discrete area or all of a user's head, ears, and forehead. The exterior-layer material has some elastic stretch. The interior layer material is a blend having both elastic and wicking properties. The interlayer space has no seams creating barriers to the exact positioning of a thermal pack where it is required. There is a slit throughout the interior and/or exterior-layer through which one or more discrete spot sized thermal packs or a whole head sized thermal pack is inserted. There is an optional strap for securing the hat about a head. These inventive principles include hats, scarves, and belts, for example.

Abstract: A hat having exterior and interior layers connected to each other only along the periphery of the hat creating an unobstructed interlayer space for insertion of a thermally retentive pack(s) providing for the application of heat or cold to any specific area or all of a user's head, ears, and forehead. The layers and space sized and shaped to fit about the contours of a user's entire scalp, ear, and forehead area. The interlayer space is bounded by the inner exterior and inner interior layer surfaces and a seam (forms??) from the layer's connection, and has no seams creating barriers to the exact positioning of a hot or cold pack where it is required. There is a slit throughout the interior and/or exterior layer through which a specific spot-sized or whole head-sized hot or cold pack is inserted. There is an optional strap for securing the hat about a head.
