An absorbent article comprising: a first belt comprising an inner wearer facing surface and an outer garment facing surface, the first belt further comprising a laterally extending inner edge and a laterally extending outer edge, the outer edge positioned longitudinally outward of the inner edge; a second belt, wherein laterally opposing end portions of the second belt are connected with laterally opposing end portions of the first belt at a first side seam and a second side seam to form a waist opening; a chassis comprising a topsheet, a backsheet, and an absorbent core positioned between the topsheet and the backsheet, the chassis comprising a longitudinally extending first side edge and a longitudinally extending second side edge laterally separated from the first side edge by a first end edge and a second end edge longitudinally separate from the first end edge, and wherein longitudinally opposing end regions of the chassis are connected with the first belt and the second belt; wherein a portion of the chassis overlaps the inner wearer facing surface of the first belt to define a chassis overlap region, wherein the chassis overlap region comprises an adherence region where adhesive is positioned between the chassis and the inner wearer facing surface of the first belt and permanently bonds the chassis with the first belt; wherein the adherence region comprises a first adherence zone adjacent the inner edge of the first belt, a second adherence zone adjacent the first end edge of the chassis, and a third adherence zone positioned longitudinally between the first adherence zone and the second adherence zone, wherein the first adherence zone comprises a first lateral width, the second adherence zone comprises a second lateral width, and the third adherence zone comprises a third lateral width, and wherein the third lateral width is less than the first lateral width and the second lateral width; a first frangible pathway and a second frangible pathway extending across the overlap region in opposing directions laterally outward from the third adherence zone and between the first adherence zone and the second adherence zone, wherein the first frangible pathway and the second frangible pathway do not extend across the third adherence zone; and wherein the overlap region further comprises a first pocket region and a second pocket region, wherein the first pocket region extends longitudinally between the first adherence zone and the second adherence zone and extends laterally between the third adherence zone and the first side edge of the chassis, and wherein the second pocket region extends longitudinally between the first adherence zone and the second adherence zone and extends laterally between the third adherence zone and the second side edge of the chassis, wherein no adhesive connects the chassis with the first belt in the overlap region in the first pocket region and the second pocket region.
