Abstract: A CRYLON.TM. gel containing glass beads and a light metal, formulated to be pliable when frozen, yet reusable and stable enough to permit repeated thawing and freezing, is contained within a vinyl package having a covering which is both hypoallergenic and waterproof. The packages are comfortably held in place, e.g. pressed against an injured portion of the body, by appropriate straps and/or fasteners, which may form a part of the package.
