The Natura^® ostomy system is a comprehensive product line with our latest skin barrier technologies. The plastic coupling ring allows the pouch and skin barrier to snap together for audible security. Durahesive^® skin barriers are designed for people whose stoma output is mostly liquid. Unlike other skin barriers that can breakdown around liquid output, Durahesive^® skin barriers swell up or "Turtleneck" to better protect the stoma and peristomal skin.
