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 unitary construction, which is defined by a pair of longitudinal edges (20)； (22) and by a pair of opposite transverse edges (24)； (26). the absorbent core (18) has at least one first (28) and a second (30) regions, the average density of the absorbent core (18) in these first and second regions (28), (30) being less than the average core density absorber (18) surrounding said first and second regions (28)； (30), said first and second regions (28)； (30) of lower density being symmetrically arranged over the longitudinal centerline (a) of the article such that each of the first and second regions (28)； (30) of lower density extends to its longitudinal edge (20)； (22) of the absorbent core. the distance (ax) between said first and second regions (28)； (30) of lower density in the transverse direction varying along the longitudinal direction of the article. a minimum distance (ai) between said first and second regions (28)； (30) of lower density in the transverse direction are located at least at the transition (32) between the hook portion (14) and the front portion (12). The article provides a good and safe fit and high user comfort.artigo absorvente com ajuste aperfeiçoado. 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, que é definido por um par de bordas longitudinais (20)； (22) e por um par de bordas transversais opostas (24)； (26). o núcleo absorvente (18) tem ao menos uma primeira (28) e uma segunda (30) regiões, a densidade média do núcleo absorvente (18) nestas primeira e segunda regiões (28), (30) sendo inferior à densidade média do núcleo absorvente (18) que circunda ditas primeira e segunda regiões (28)； (30), ditas pri
