A multi-component topsheet for an absorbent article, the topsheet comprising: a) a first discrete substrate; b) a second discrete substrate comprising a first hydrophobic nonwoven layer and a second hydrophilic nonwoven layer; and c) a third discrete substrate; wherein the second discrete substrate is disposed at least partially intermediate the first discrete substrate and the third discrete substrate; wherein the second discrete substrate is joined to the first discrete substrate and the third discrete substrate; wherein the topsheet has a single layer of substrate in 80% or more of the total area of the topsheet and a dual layer of substrate in 20% or less of the total area of the topsheet; wherein a first dual layer area is formed from an overlap between the first discrete substrate and the second discrete substrate; wherein a second dual layer area is formed from an overlap between the second discrete substrate and the third discrete substrate; wherein the first and second dual layer areas together form the dual layer of substrate; and wherein the second discrete substrate comprises a plurality of recesses and projections, wherein the plurality of recesses and projections together form a first three-dimensional surface on a first side of the second discrete substrate and a second three-dimensional surface on a second side of the substrate, wherein the plurality of projections form enclosed dome shapes, wherein a majority of the projections are formed by the first and second nonwoven layers, wherein the majority of the projections have, according to the Projection Height Test, a z-dimensional height of between 500 μm and 4000 μm, and wherein a majority of the recesses define an aperture at a location most distal from a top surface of an adjacent projection, a majority of the recesses having, according to the Recess Height Test, a z-directional height of between 500 μm and 2000 μm.
