FIELD: hygiene.SUBSTANCE: present invention relates to a disposable absorbent article (1) such as underpants, hygienic pants or incontinent panties for an adult user. Absorbent product (1) has longitudinal direction (Y) and transverse direction (X). Also, the absorbent product comprises a front body panel (3) having waist edge (20), a pair of foot edges (21a, 21b) and a pair of side edges (9a, 9b), a body rear panel (4) having waist edge (25), a pair of foot edges (27a, 27b), a pair of side edges (10a, 10b), main section (28) and section (29) covering the buttocks, and absorbing insert (2) located mainly in perineal part (70) of absorbent product (1) and connected to panels for front and rear body parts (3, 4) with overlapping gap between panels (3, 4) for front and rear body parts. Absorbing insert (2) comprises absorbent core (5). Panels (3, 4) for front and rear body parts are also connected to each other on opposite lateral edges (9a, 10a, 9b, 10b) to at least partially define waist hole (7) and pair of foot holes (8). Front body panel (3) has a first at least partially elastic region (11) extending along foot edges (21a, 21b) of the front body panel (3) and a second at least partially elastic region (12) located after first elastic region (11). Panel (4) for the posterior part of the body comprises a third elastic region (13) extending at least partially along section (29) covering the buttocks, panels (4) for the posterior part of the body. Each of said elastic areas (11–13) is made elastic by means of a plurality of elastic threads (11T-13T) located substantially in transverse direction (X) on the main part of the panel for the front or rear parts of body (3, 4). Lateral edge (13L1) of the third elastic region (13) overlaps in the longitudinal direction (Y) both lateral edge (11L) of the first at least partially elastic region (11) and the part of side edge (12L) of the second, at least, partially elastic area (12) on side seams (6a, 6b).EFFECT: disclosed is
