The disposable absorbent article includes a liquid pervious topsheet, a liquid impervious backsheet joined to the topsheet, and an absorbent core positioned between the topsheet and the backsheet. Since the first region is juxtaposed with the of the wearer it should be superior in the handling of urine while the second region which is juxtaposed with the back of the wearer should be superior in the handling of low-viscosity fecal material. The first region has a PACORM value of less than 120 mg and the second region has a trans-topsheet capacity of at least 0.2 grams per square inch.
