A reusable pad comprising: a fabric top layer having a user-side surface for being situated adjacent a user and including a multifilament yarn, the top layer having a plurality of spaced apart openings formed therethrough and having a chemical treatment composition applied thereto, the chemical treatment composition including one or more hydrophobic chemical compounds and/or one or more chemical compounds that impart hydrophobic properties to the top layer, wherein the chemical treatment composition provides a desired hydrophobicity to the top layer such that liquid from the user passes through the user-side surface of the top layer via only the spaced apart openings; a bottom barrier layer that includes an impermeable layer; and a first wicking layer situated between the top layer and the bottom barrier layer, the first wicking layer including a plurality of first wicking layer sub-layers including one or more plies of multifilament hydrophobic yarn with one sub-layer being adjacent the top layer and each of the plurality of sub-layers having a corresponding dpf (denier per filament) value wherein the dpf values for each sub-layer increases when moving in a direction away from the top layer to provide a capillary gradient that promotes migration of liquid from the user in a direction away from the top layer.
