The Hollister Premier One-Piece Closed Ostomy Pouch – Flat SoftFlex Barrier, Filter is a one-piece, closed pouching system designed to be removed after use. These pouches are most suitable for colostomies or for stomas with less frequent or more predictable output. The SoftFlex barrier is a standard wear skin barrier that is gentle to the skin and allows for frequent pouch removal. The AF300 filter allows for a slow release and deodorization of gas from the pouch. Soft, beige ComfortWear pouch panels help provide comfort.
