The absorbent article comprises a liquid permeable first topsheet layer having first topsheet layer opposing lateral side edges, and first topsheet layer opposing longitudinal ends as well as a liquid permeable second topsheet layer subjacent to the liquid permeable first topsheet layer. The liquid permeable second topsheet layer has second topsheet layer opposing lateral side edges, and second topsheet layer opposing longitudinal ends, and is attached at or along two opposing attachment zones to the liquid permeable first topsheet layer along or adjacent the first topsheet layer opposing lateral side edges. ## Claims ### Claim 1 An absorbent article having a longitudinal direction, a transverse direction, and a depth direction, said absorbent article having absorbent article opposing first and second longitudinal ends, and absorbent article opposing lateral side edges extending between said absorbent article opposing first and second longitudinal ends, said absorbent article comprising: a liquid permeable first topsheet layer having first topsheet layer opposing lateral side edges, and first topsheet layer opposing longitudinal ends; a liquid permeable second topsheet layer subjacent, along said absorbent article depth direction, to said liquid permeable first topsheet layer, said liquid permeable second topsheet layer having second topsheet layer opposing lateral side edges, and second topsheet layer opposing longitudinal ends, and being attached at two opposing attachment zones to said liquid permeable first topsheet layer along or adjacent said first topsheet layer opposing lateral side edges, such that said liquid permeable first topsheet layer is unattached to said liquid permeable second topsheet layer at said first topsheet layer opposing longitudinal ends, and further such that continuous unattached areas are present at least partially across the absorbent article transverse direction between said two opposing attachment zones, said first and second liquid permeable topsheet layers being unattached from one another at said continuous unattached areas; a liquid impermeable backsheet layer; at least one absorbent core layer sandwiched between said liquid permeable second topsheet layer and said liquid impermeable backsheet layer along the absorbent article depth direction; wherein said liquid permeable first topsheet layer is apertured such that there is at least one uninterrupted aperture opening extending through the entire thickness of said liquid permeable first topsheet layer to said liquid permeable second topsheet layer; and wherein said article includes an additional layer subjacent to said liquid permeable second topsheet layer in the article depth direction, said additional layer including an aperture opening that is aligned with said aperture opening of said liquid permeable first topsheet layer along the article depth direction, and is sized and shaped similarly to said first topsheet layer aperture opening. ### Claim 2 (depends on 1) The absorbent article of claim 1 wherein said liquid permeable second topsheet layer is relatively more hydrophilic than said liquid permeable first topsheet layer. ### Claim 3 (depends on 1) The absorbent article of claim 1, wherein said liquid permeable first topsheet layer includes a bend line along said absorbent article longitudinal direction. ### Claim 4 (depends on 3) The absorbent article of claim 3, wherein said liquid permeable first topsheet layer includes two side surfaces, and further wherein said bend line is an embossed line that is present on one or both side surfaces of said liquid permeable first topsheet layer. ### Claim 5 (depends on 3) The absorbent article of claim 3, wherein said absorbent article includes a central longitudinal direction, and said bend line is positioned along said central longitudinal direction. ### Claim 6 (depends on 3) The absorbent article of claim 3, wherein said at least one uninterrupted aperture opening is positioned along said bend line. ### Claim 7 (depends on 3) The absorbent article of claim 3, wherein said liquid permeable first topsheet layer includes multiple, similarly sized and shaped uninterrupted aperture openings. ### Claim 8 (depends on 3) The absorbent article of claim 3, wherein said liquid permeable first topsheet layer includes multiple, similarly shaped uninterrupted aperture openings of at least two different sizes. ### Claim 9 (depends on 3) The absorbent article of claim 3, wherein said liquid permeable first topsheet layer includes a centrally located, single oval or circular shaped, uninterrupted aperture opening. ### Claim 10 (depends on 3) The absorbent article of claim 3, wherein said liquid permeable first topsheet layer includes a user-facing, skin contacting surface and an opposing garment-facing surface, with said garment-facing surface having a non-absorbent, fluid transfer layer attached thereto. ### Claim 11 (depends on 10) The absorbent article of claim 10, wherein said fluid transfer layer includes at least one aligned aperture opening that is of the same shape and size as said at least one uninterrupted aperture opening of said fluid permeable first topsheet layer. ### Claim 12 (depends on 11) The absorbent article of claim 11, wherein said one aligned aperture opening is of a single oval or circular shape. ### Claim 13 (depends on 3) The absorbent article of claim 3, further including an additional apertured, liquid permeable topsheet layer having a longitudinal and transverse direction, said additional apertured, liquid permeable topsheet layer situated between said liquid permeable first and second topsheet layers, said additional apertured topsheet layer being attached along the full longitudinal and transverse directions of the additional apertured topsheet layer to said liquid permeable first topsheet layer. ### Claim 14 (depends on 13) The absorbent article of claim 13, wherein said additional apertured, liquid permeable topsheet layer includes multiple shaped and sized apertures. ### Claim 15 (depends on 3) The absorbent article of claim 3, wherein said liquid permeable first topsheet layer includes folds adjacent each of the first topsheet layer opposing lateral side edges. ### Claim 16 (depends on 3) The absorbent article of claim 3, wherein said liquid permeable first topsheet layer is attached to said liquid permeable second topsheet layer adjacent the second topsheet layer opposing lateral side edges, through at least one bonding method selected from the group consisting of adhesive, ultrasonic, and thermal bonding methods. ### Claim 17 (depends on 3) The absorbent article of claim 3, wherein said liquid permeable first topsheet layer includes a liquid permeable first topsheet layer, longitudinal and transverse direction, wherein said liquid permeable second topsheet layer includes a liquid permeable second topsheet layer longitudinal and transverse direction, and said liquid permeable first topsheet layer differs in dimension from said liquid permeable second topsheet layer at least along one of the transverse or longitudinal direction. ### Claim 18 (depends on 17) The absorbent article of claim 17 wherein said liquid permeable first topsheet layer differs in dimension from said liquid permeable second topsheet layer along both transverse and longitudinal directions. ### Claim 19 (depends on 18) The absorbent article of claim 18 wherein the liquid permeable first topsheet layer is shorter along the absorbent article longitudinal direction than said liquid permeable second topsheet layer. ### Claim 20 (depends on 1) The absorbent article of claim 1, wherein said liquid permeable first topsheet layer is hydrophobic.
