1. An absorbent article comprising:
an outer cover;
a body facing material;
an absorbent body disposed between the outer cover and the body facing material; and
a secondary liner disposed between the body facing material and the absorbent body, wherein the secondary liner overlays the absorbent body and extends beyond the absorbent body to enclose the absorbent body between the secondary liner and the outer cover, the secondary liner having a basis weight of between 10 qsm and 20 gsm;
wherein the body facing material comprises:
a first layer comprising a first plurality of fibers and having a first surface and an opposed second surface, the first layer having a basis weight of between about 10 qsm to about 20 gsm;
a second layer having a basis weight that is higher than the basis weight of the first layer and is between about 25 qsm and about 50 gsm and comprising a second plurality of fibers and having an inner surface and an opposed outer surface, wherein portions of the second surface of the first layer are in contact with the inner surface of the second layer, wherein at least a portion of the first plurality of fibers or the second plurality of fibers are fluid-entangled with at least a portion of the other of the first plurality of fibers or the second plurality of fibers;
a plurality of projections formed from at least a portion of the second plurality of fibers, the plurality of projections extending from the outer surface of the second layer in a direction away from the first layer; and
a land area disposed between and surrounding the plurality of projections,
wherein the projections have an open area of less than 1% in a chosen area; and
wherein the land area has an open area greater than about 10% open area in a chosen area, the chosen land area including both apertures and interstitial fiber-to-fiber spacing to achieve the greater than about 10% open area.
