The SUR-FIT Natura Durahesive Moldable Skin Barrier is part of the latest in skin barrier technology. Moldable barriers allow for improved skin protection over traditional barriers and provide ease of use and versatility. Durahesiveskin barriers are designed for people whose stoma output is mostly liquid. Unlike other skin barriers that can break down around liquid output, Durahesive skin barriers swell up or "Turtleneck" to better protect the stoma and peristomal skin. The plastic coupling ring allows the pouch and skin barrier to snap together for audible security. Convex barriers are good for people with a retracted or flush stoma. These models require no cutting or measuring, which makes it easy to learn how to use.
