    An absorbent article comprising: a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent core between the topsheet and backsheet, the absorbent core comprising a core wrap enclosing an absorbent material, the absorbent material comprising a superabsorbent polymer, wherein the core wrap comprises a top side and a bottom side, wherein the absorbent core comprises one or more areas substantially free of absorbent material through which the top side of the core wrap is attached to the bottom side of the core wrap, so that when the absorbent material swells the core wrap forms one or more channels along the areas substantially free of absorbent material, and wherein the absorbent core is void of areas substantially free of absorbent material which are transversely oriented; and the absorbent article further comprising a fibrous layer, wherein the fibrous layer is at least partially bonded to the top side or the bottom side of the core wrap in the area substantially free of absorbent material such that the fibrous layer at least partially fills the area substantially free of absorbent material, so that the formation of the channel in the absorbent core as the absorbent material swells causes the formation of one or more corresponding ditches in the fibrous layer.
