The outer skirt includes a tissue layer and a non-tissue layer. The tissue layer has a fibrous side and a smooth side. The non-tissue layer is coupled to the smooth side of the tissue layer. The outer skirt is positioned so that the fibrous side of the tissue layer faces away from the frame and the non-tissue layer faces towards the frame.
