Abstract: This invention concerns a device applied with a cast for immobilizing an injured limb. A comfort band is applied as a length of cotton tape or other flexible fabric material longitudinally of the limb with the ends of the tape protruding beyond the proximal and distal ends of the zone to be cast. The zone to be cast is then wrapped in an absorbent cotton mesh and padding is applied exteriorly of the mesh. The absorbent mesh and padding together form a cast building substrate. A settable cast forming material is applied to the substrate and allowed to set. Gripping the protruding ends of the comfort band allows movement of the comfort band in the space normally provided between the cast and limb to alleviate epidermal irritation.
