It is designed to maintain adhesive properties and features a formulation designed to help protect the skin's natural moisture barrier and help maintain good peristomal skin health. The integrated Lock 'n Roll microseal closure utilizes plastic interlocking fasteners to create a secure closure at the bottom of the pouch. The AF300 filter allows for a slow release and deodorization of gas from the pouch.
