1. An absorbent article comprising:
a central longitudinal axis;
a liquid permeable topsheet;
a backsheet; and
an absorbent core positioned at least partially intermediate the topsheet and the backsheet, wherein the absorbent core comprises an absorbent material comprising superabsorbent polymers;
the topsheet comprising:
a first layer comprising a hydrophobic nonwoven material, wherein the hydrophobic nonwoven material overlaps the central longitudinal axis of the absorbent article, and wherein the first layer comprises carded fibers; and
a second layer comprising a hydrophilic nonwoven material, wherein the first layer is joined to the second layer, and wherein the second layer comprises carded fibers;
wherein the topsheet comprises a plurality of recesses, a plurality of dome-shaped projections forming a portion of a wearer-facing surface of the topsheet, and a plurality of land areas, wherein the land areas surround at least a majority of the plurality of dome-shaped projections and a plurality of the recesses, wherein the plurality of recesses, the plurality of dome-shaped projections, and the plurality of land areas, together form a first three-dimensional surface on a first side of the topsheet and a second three-dimensional surface on a second side of the topsheet, wherein a majority of the projections have a z-directional height in the range of about 500 μm to about 4000 μm, according to the Projection Height Test, wherein a majority of the recesses define an aperture at a location most distal from a top peak of an adjacent dome-shaped projection and defined at a lowermost plane of the topsheet, and wherein the majority of the recesses have a z-directional height in the range of about 500 μm to about 2000 μm, according to the Recess Height Test;
wherein the topsheet has an overall z-directional height in the range of about 1000 μm to about 6000 μm, according to the Overall Substrate Height Test; and
wherein the apertures are formed through the first layer and the second layer.
