Absorbent article

An absorbent article comprising longitudinal side edges, transversal end edges, a fluid permeable topsheet, a fluid impermeable backsheet, and an absorbent core located between the topsheet and the backsheet, the absorbent core comprising a first absorbent layer having a longitudinal front portion and a longitudinal back portion, the first absorbent layer having an opening extending therethrough and 20-50% of the longitudinal length of the opening located in the front portion of the first absorbent layer, a fluid flow control structure being located between the first absorbent layer and the backsheet, and an elastic member being arranged along each longitudinal side edge of the absorbent article, wherein

• a narrow transversal transition is located between the front portion and the back portion of the first absorbent layer, the width of the narrow transversal transition is 50-75% of the widest transversal width of the front portion of the first absorbent layer, the front portion of the first absorbent layer constitutes 20-40% of the total longitudinal length of the first absorbent layer, and an interspace is located in an area between the elastic member and the first absorbent layer at least in an area laterally outside the narrow transversal transition.
