An absorbent article having a primary topsheet, a backsheet, and an absorbent system therebetween is described. The primary topsheet has a body-facing surface and a garment-facing surface, and the backsheet has a body-facing surface and garment-facing surface. The absorbent system includes a first absorbent core having a body-facing surface and a garment-facing surface, and a second absorbent core disposed between the first absorbent core and the backsheet. The primary topsheet and at least a portion of the first absorbent core has one or more embossed channels including a central channel disposed on the body-facing surface of the primary topsheet. Each of the one or more embossed channels has a bottom surface subjacent to the body-facing surface of the primary topsheet and superjacent to the first absorbent core garment-facing surface.

An absorbent article such as a diaper extending in a longitudinal direction parallel to a longitudinal axis (80′) and a transversal direction (90′) perpendicular to the longitudinal direction and comprising a distribution layer (54) between a topsheet (24) and an absorbent core (28). The distribution layer comprises a fibrous material and a first and second longitudinally-extending channels (86a,b) substantially free of fibrous material. The fibrous material is profiled in the transversal direction so that average basis weight between the channels differs from the average basis weight in the lateral areas outward of the channels by at least 50 g/m.sup.2 and/or wherein the distribution layer comprises a first region having a first basis weight (bw1) and a second region having a second basis weight (bw2), wherein the first basis weight and the second basis weight differ by at least 20 g/m.sup.2, preferably by at least 50 g/m.sup.2, and these regions are present in different areas of the distribution layer but in the same longitudinally extending transversal section. The absorbent core may comprise channel-forming areas (26a,b). The article further comprises a backsheet (25).
