absorbent article with improved fit. The present invention relates to an absorbent article (10) having front (12), hook (14) and rear (16) portions. The article comprises an absorbent core (18) of uniform construction and uniform density, which is defined by a pair of opposite longitudinal edges (20, 22) and a pair of opposite transverse edges (24, 26). the absorbent core (18) has at least one first region (28) and a second (30) region, the average thickness of the absorbent core (18) in these first and second regions (28, 30) being less than the average thickness of the absorbent core. (18) surrounding said first and second regions (28, 30), said first and second regions of lower thickness (28, 30) being arranged symmetrically with respect to the longitudinal center line a of the article such that each of the first and second The second lower thickness regions (28, 30) extends to the respective longitudinal edge (20, 22) of the absorbent core. the distance (s) between said first and second regions of lower thickness (28, 30) in the transverse direction varying along the longitudinal direction of the article. a minimum distance (therein) between said first and second transverse thickness regions (28, 30) being at least at the transition (32) between the hook portion (14) and the front portion (12). The article provides good and safe fit and high user comfort.artigo absorvente com ajuste melhorado. a presente invenção se refere a um artigo absorvente (10) possuindo porções dianteira (12), de gancho (14) e traseira (16) . o artigo compreende um núcleo absorvente (18) de construção unitária e de densidade uniforme, que é definido por um par de bordas longitudinais opostas (20, 22) e por um par de bordas transversais opostas (24, 26) . o núcleo absorvente (18) tem ao menos uma primeira região (28) e uma segunda (30) região, a espessura média do núcleo absorvente (18) nestas primeira e segunda regiões (28, 30) sendo inferior à espessura média do núcleo absorvente (18) ci
