An absorbent article comprising: a three-dimensional, liquid permeable topsheet comprising: a first nonwoven layer forming a portion of a wearer-facing surface of the absorbent article, wherein the first nonwoven layer comprises a hydrophobic material; and a second nonwoven layer comprising a hydrophilic material, wherein the first nonwoven layer is joined to the second nonwoven layer; wherein the topsheet comprises a plurality of recesses, a plurality of projections, and a plurality of land areas, wherein the land areas surround at least a majority of the plurality of projections and a plurality of the recesses, wherein the plurality of recesses, the plurality of 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 projection, 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 600 μm to about 6000 μm, according to the Overall Substrate Height Test; wherein a portion of the projections and a portion of the recesses are formed by a portion of the first nonwoven layer and a portion of the second nonwoven layer; wherein the apertures are formed through the first nonwoven layer and through the second nonwoven layer; wherein the topsheet has a basis weight in the range of about 20 gsm to about 50 gsm, according to the Basis Weight Test; a liquid impermeable backsheet; a material positioned at least partially intermediate the topsheet and the backsheet; and an acquisition material positioned at least partially intermediate the topsheet and the material; wherein the topsheet comprises a first Median Absorption Pressure having a first value; wherein the acquisition material comprises a Median Absorption Pressure having a second value; wherein the material comprises a third Median Absorption Pressure having a third value; wherein the second value is intermediate or equal to the first value and the third value; wherein the topsheet has an equilibrium capillary suction sorbent capacity greater than 10 g/g at 100% saturation, according to the Capillary Sorption Test; and wherein the acquisition material has an equilibrium capillary suction sorbent capacity less than 7 g/g at 100% saturation, according to the Capillary Sorption Test.
