1. A plant-based absorbent article comprising a plurality of layers, the plurality of layers consisting of:
(i) a first layer having a first user-facing surface and a first non-user-facing surface, wherein the first layer is a top sheet consisting of 100% cotton providing a natural hydrophobic fiber layer adjacent to a user's skin and configured to allow fluid to rapidly pass through;
(ii) a second layer having a second user-facing surface and a second non-user-facing surface, wherein the second user-facing surface is immediately adjacent to and in direct contact with the first non-user-facing surface with no intervening layers, and wherein the second layer is an acquisition/distribution layer (ADL) consisting of two sub-layers of different materials, wherein a first sub-layer is an apertured film acquisition layer and a second sub-layer is a non-woven distribution layer, wherein the first sub-layer is immediately adjacent to and in direct contact with the second sub-layer with no intervening sub-layers, and
wherein the apertured film acquisition layer includes perforations that form funnels configured to provide a circuitous path for fluid flow and oriented to prevent fluid flow back towards the first layer;
(iii) a third layer having a third user-facing surface and a third non-user-facing surface, wherein the third user-facing surface is immediately adjacent to and in direct contact with the second non-user-facing surface with no intervening layers, and wherein the third layer is an absorbent core configured to receive and trap the fluid flowing from the second layer; and
(iv) a fourth layer having a fourth user-facing surface and a fourth non-user-facing surface, wherein the fourth user-facing surface is immediately adjacent to and in direct contact with the third non-user-facing surface with no intervening layers, wherein the fourth layer is a liquid impermeable barrier configured to contain the fluid received and trapped in the absorbent core while allowing air to transfer between the outside environment and the plurality of layers.
