A temperature pack adapted to enclose an appendage, and method of forming such a temperature pack is provided. The temperature pack is a tubular pouch with an inner wall spaced apart from an outer wall. An opening extending through the tubular pouch, and the inner wall is twisted relative to the outer wall. The temperature pack is formed by rolling a tube onto itself such that the distal ends of the tube are aligned to each other. The temperature pack may be filled with particulate material separated from a liquid solvent wherein when the two are mixed an exothermic or endothermic reaction occurs.
