1. A disposable absorbent article comprising:
a non-woven inner layer consisting of natural fibers;
a hydrophobic non-woven outer layer, the hydrophobic non-woven outer layer consisting of:
natural fibers treated with an internal hydrophobic agent; and
an external hydrophobic surface treatment applied to a surface of the non-woven outer layer, the external hydrophobic surface treatment selected from the group consisting of waxes, urethanes, silicones, fluorocarbons, non-fluorochemical repellants applied to at least one surface thereof;
a core comprising natural fibers or fibrous material positioned between the inner layer and the outer layer, and
an acquisition/distribution layer comprised of polylactic acid between the non-woven inner layer and the core.
