The Hollister 8551 colostomy pouch is flat, discreet and suitable for exercise. Trim-to-fit design makes it possible to match the skin barrier to stoma size and shape to improve comfort and prevent leak. Interlocking fasteners produce secure closure to keep this drainable ostomy pouch from leaking. Flextend skin barrier is durable and, along with a tape border, keeps the pouch system securely in place.
