15-BOXES ConvaTec Sur-Fit Natura Two-Piece OPAQUE DRAINABLE POUCH with Two-Sided Comfort Panel and Filter (411492) 20 ct Compatible with the Moldable Skin Barrier (404594) The Sur-Fit Natura 2-piece ostomy system is ConvaTec’s most extensive 2-piece product line. The Sur-Fit Natura flange system signals a secure, accurate closure with a series of audible „clicks.“ A simple snap-off, snap-on design allows users to change the pouch quickly to match activities without removing the skin barrier from the skin. The drainable pouches have soft, fabric-like comfort panels. With streamlined body contour panels, low-profile design, and less headroom, they distribute pouch content more evenly and away from the stoma.
