Fitted briefs are tab-style diapers for youths or adults that can be refastened with either tape or velcro style tabs. All feature a waterproof backing made from either the traditional plastic (poly) material or the softer non-woven cloth-like material. Many customers prefer fitted brief style diapers if the pull-on style is leaking out the legs or if the patient needs assistance from a caregiver, especially at night.
