Hollister CenterPointLock - 9" 2-Piece Closed Ostomy Pouch with Filter has a four layer construction that offers a rustle free odor-barrier film to minimize pouch noise and rustling for added discretion. The secure CenterPointLock
system helps prevent accidental separation between the pouch and the skin barrier. A unique, activated carbon filter deodorizes and vents gas from inside the pouch, offering additional comfort and peace of mind.
