Abstract

A breathable interface system including an applicator having an aperture therethrough; a drape substantially covering the applicator; a first pad section located between the drape and the applicator; a second pad section substantially covering the aperture and located between the drape and the applicator, the second pad section substantially adjacent to the first pad section; and a fabric layer located at least partially between the second pad section and the drape; and a reduced pressure conduit in communication with one of the first pad section and the fabric layer for providing reduced pressure to the aperture; wherein the drape is secured to the applicator, covering the first pad section, the second pad section, and the fabric layer in a substantially sealed environment.
