ABSTRACT:
An absorbent article includes a garment facing surface which includes a first zone of vapor permeability which defines a water vapor transmission rate of from about 100 to about 2500 g/sq.m/24 hr and a second zone of vapor permeability which defines a water vapor transmission rate of at least about 3000 g/sq.m/24 hr. The article may include a substantially liquid impermeable, vapor permeable backsheet, a liquid-permeable topsheet positioned in facing relation with the backsheet, an absorbent body located between the backsheet and topsheet, and a vapor permeable barrier layer located between the absorbent body and the backsheet. The barrier layer is smaller in size than the backsheet. In such a configuration, the first zone of vapor permeability comprises the portion of the backsheet which overlays the barrier layer and the second zone of vapor permeability comprises the portion of the backsheet which extends beyond the barrier layer.
