A flexible covering for placing over an individual's injured limb having a cast or bandage. The covering consists of a tubular piece of flexible material, one end of which is open and the other end of which is closed in a receptacle for the hand or foot of the individual. The tube tapers into a neck at its open end so as to provide a sealing portion which snugly engages the limb of the individual above the upper termination of the cast or bandage. The sealing portion or neck has an interior diameter smaller than the diameter of the limb above the cast or bandage in order to provide a sealing engagement with the limb. The covering is designed for use by the individual with the injured limb when he is bathing in order to protect the cast or bandaged area from contact with water.
