1. A multi-component topsheet for an absorbent article, the topsheet comprising:

  • a) a first discrete substrate forming 80% or more of an outer perimeter of the topsheet; and

    b) a second discrete substrate comprising a first hydrophobic nonwoven layer and a second hydrophilic nonwoven layer, wherein 80% or more of an outer perimeter of the second discrete substrate is joined to the first discrete substrate;

    wherein the topsheet has a single layer of substrate in 75% or more of the total area of the topsheet and a dual layer of substrate in 25% or less of the total area of the topsheet;

    wherein the dual layer of substrate is formed from an overlap between the first discrete substrate and the second discrete 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 a majority of the projections are formed by the first and second nonwoven layers, wherein the plurality of projections form enclosed dome shapes, wherein the majority of the projections have, according to the Projection Height Test, a z-dimensional height of between 500 μ

    m and 4000 μ

    m, 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 μ

    m and 2000 μ

    m.
