Absorbent article
An absorbent article has longitudinal side edges, transversal end edges, and an absorbent core. The absorbent core comprises a first absorbent layer having an opening and a fluid flow control structure between said first absorbent layer and a backsheet. An elastic member is arranged along each longitudinal side edge. The first absorbent layer has a longitudinal front portion, a longitudinal back portion and a narrow transversal transition located between said front and back portions. The width of the narrow transversal transition is 50-75% of the widest transversal width of the front portion, and 20-50% of the longitudinal length of the opening is located in the front portion. The front portion constitutes 20-40% of the total longitudinal length of the first absorbent layer. 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.
1. 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, a second absorbent layer located between the fluid flow control structure and the backsheet, the second absorbent layer having a smaller surface area than the first absorbent layer, 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.

12. Absorbent article according to claim 1 , wherein the topsheet and the backsheet extend together laterally outside of the first absorbent layer.
13. Absorbent article according to claim 1 , wherein the transverse dimension of the opening is larger in the front portion of the first absorbent layer than the transverse dimension of the opening in the back portion of the first absorbent layer.
14. Absorbent article according to claim 1 , wherein each longitudinal side edge is an outermost edge of the absorbent article, and each elastic member is provided at the outermost edge.
15. Absorbent article according to claim 1 , wherein the interspace extends along the elastic member so that the elastic member does not overlap the first absorbent layer.
