Abstract: A waterproof covering intended to be worn over a cast or bandage on an injured arm or leg. The covering comprises a generally tubular water impervious sleeve which is closed at one end and which has spaced cutting sites running from side to side along which the sleeve can be cut to different lengths. Apertured tabs are provided along the length of the covering to receive a strap for encircling the covering and sealing the covering around the limb, when the covering is cut at the cutting sites. Visual indicators identify the cutting sites. Additional seam segments serve to provide resistance to tearing at side edges.
