The first sheet and the second sheet extend beyond the core and are joined together to form a seal. The absorbent core has at least 40% superabsorbent. The absorbent insert has an intake layer of at least 100 gsm between the first sheet and the absorbent core. The first sheet and the second sheet are fluid permeable, spunbond webs of synthetic polymer filaments. The absorbent insert is devoid of a fluid-impervious layer and has an absorbent capacity of at least 600 g. The first end section of the absorbent core has a maximum width of at least 135 mm, the central section of the absorbent core has a maximum width of less than 90 mm, and the second end section of the absorbent core has a maximum width of at least 135 mm.
