A disposable absorbent article having a topsheet, a backsheet, and an absorbent core structure disposed therebetween. The absorbent core structure includes an upper nonwoven layer comprising polymer fibers and having a basis weight of from about 30 to about 85 gsm; a lower nonwoven layer comprising polymer fibers; and an inner core layer disposed between the upper and lower nonwoven layers. The inner core layer comprises a mixture of cellulose pulp and superabsorbent particles. The cellulosic pulp comprises from about 25% to about 70% of a short cellulosic fiber, by weight of the cellulose pulp, wherein the short cellulosic fiber has an average fiber length of less than about 2 mm. The absorbent core structure has an average density of between about 0.045 g/cm.sup.3 and about 0.15 g/cm.sup.3. At least a portion of the inner core layer is contained within the nonwoven layers by sealing a portion of a first and second side region of the upper and lower nonwoven layers.
