The present invention is directed to an absorbent structure comprising an integral absorbent element with an upper surface and a lower surface defining a thickness therebetween. The thickness has an upper 35% containing a high absorbency zone and a lower 65%. The high absorbency zone has a first surface and a second surface separated by a zone thickness. The zone thickness is less than about 35% of the absorbent element thickness. The high absorbency zone comprises absorbent fibers and superabsorbent polymer particles. The superabsorbent polymer particles are present at a loading of no more than 75 grams per square meter and are separated from one another by the absorbent fibers. The lower 65% of the absorbent element thickness is substantially free of superabsorbent polymer particles.
