Hollister Wound Drainage Pouch Moderma Flex is a one-piece, drainable pouching system designed to be opened at the bottom when emptying. Hollister Ostomy Bags Moderma Flex are most suitable for colostomies or ileostomies. The SoftFlex barrier is a standard wear skin barrier that is gentle to the skin and allows for frequent pouch removal. The Lock ’n Roll closure utilises plastic interlocking fasteners to create a secure closure at the bottom of the pouch. The AF300 filter allows for slow release and deodorization of gas from the pouch. Soft, beige ComfortWear pouch panels help provide comfort.
