A disposable absorbent article is disclosed having a wide breathable backsheet formed of a single layer of material, preferably in an hourglass configuration, and a narrow containment assembly attached to the backsheet along its longitudinal axis. The placement of the containment assembly creates two regions on either side of the backsheet which form wings which extend laterally beyond the margins of the containment assembly. Fasteners provided on the wings permit attachment of the wings together to form breathable side panels. The fasteners may be configured to engage limited areas of the backsheet and to resist engagement of other areas thereof. The containment assembly comprises a pervious topsheet and an impervious backing film sandwiching an absorbent core. The backing film is generally as narrow as the top sheet, maximizing the breathable area of the absorbent article, and minimizing the use of environmentally persistent plastic films.
