Quick-release casts are presented. A cast can include multiple layers of material. An inner layer comprising a soft material contacts an affected limb and forms a padded layer. One or more additional layers can wrap around the padded layer to form nested tubular casts. The materials used to form the tubular casts are preferably impregnated with a curable compound capable of hardening to provide rigid support for the limb. Each of the tubular casts can wrap around the affect limb and have an overlapping seam that permanently seals in position upon curing of the curable compound. Each of the tubular casts can include a quick-release fastener that pre-joins sections of the tubular casts together before application to the limb. After the limb heals, the fastener can be undone to remove the cast quickly, quietly, and comfortably without causing undue distress to the patient.
