Abstract: A cover for an ostomy pouch of the type which is attached to a fitting secured to the skin of a patient's abdomen. The cover is made of soft, absorbent, thin, flexible fabric and has a back panel which is secured along its sides to a front panel to form a tube section. The front panel has a flap extension at its top, formed of the same material. The tube section is drawn over and around the bottom of the pouch, so that the back panel lays flat between the user's skin and the pouch, and extends up to the fitting. The flap is drawn up and folded over the waistband of the user's underpants, to be flat in front of it, between the underpants and the user's outerwear. The flap in this manner quickly and easily holds the upward opening of the tubular section in place about the pouch, without it slipping downward, while the user may engage in normal activities, such as walking, running, reaching, etc.
