The invention concerns an absorbent article comprising at least one liquid-permeable layer material (105) and an absorbent structure (106), the absorbentstructure (106) having the ability to expand on wetting, which entails that theabsorbent structure (106) displays a first volume in dry condition and a secondvolume in completely expanded wet condition, the second volume being greaterthan the first volume. The liquid-permeable layer material (105) encloses theabsorbent structure (106) so that the absorbent structure (106) is preventedfrom reaching complete expansion during wetting.
