MEDMART's ShowerShield makes all other shower collars or shields obsolete! After careful design, MEDMART now offers a stoma shield that goes on and off in seconds. This is not a tieback style, it simply offers a perfect fit with our unique Velcro fastener. Made from a lightweight, medically approved vinyl, this rubber collar stoma shield remains soft, pliable and most of all very comfortable. Accommodates neck circumferences: 15.5 inches (39.37 cm) to 22 inches (55.88 cm). Note: Do not use for swimming.
