1. A multi-component topsheet for an absorbent article, the topsheet comprising:
- a) a first discrete substrate forming about 80% or more of an outer perimeter of the topsheet; and
b) a second discrete substrate wherein about 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 about 75% or more of the total area of the topsheet and a dual layer of substrate in about 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 have, according to the Projection Height Test, a z-dimensional height of between about 500 μ
m and about 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 about 500 μ
m and about 2000 μ
m.
