An absorbent article comprising: a longitudinal and transverse dimension; a front waist region comprising a front waist edge; a rear waist region comprising a rear waist edge; a crotch region extending between the front and rear waist region; a center chassis comprising a first transverse chassis end edge, a second transverse chassis end edge, a first longitudinal chassis side edge and a second longitudinal chassis side edge, a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed between the topsheet and the backsheet; a front belt comprising a first front belt layer disposed on an interior surface of the front belt, a second front belt layer disposed on an exterior surface of the front belt, and elastic strands substantially extending along the transverse direction disposed between the first and second front belt layer; wherein the elastic strands of the front belt comprise a first plurality of elastic strands attached to one or both of the first and second front belt layers at or adjacent the transversally opposing ends of the first plurality of elastic strands; wherein the elastic strands of the front belt further comprise a second plurality of elastic strands attached to one or both of the first and second front belt layers along substantially the complete length of the elastic strands; a rear belt comprising a first rear belt layer disposed on an interior surface of the rear belt, a second rear belt layer disposed on an exterior surface of the rear belt, and elastic strands substantially extending along the transverse direction disposed between the first and second rear belt layers; wherein the elastic strands of the rear belt comprise a third plurality of elastic strands stands that are attached to one or both of the first and second rear belt layers at or adjacent the transversally opposing ends of the third plurality of elastic strands; and wherein the elastic strands of the rear belt further comprise a fourth plurality of elastic strands that are attached to one or both of the first and second rear belt layers along substantially the complete length of the elastic strands wherein the front belt has a central front belt zone, a first peripheral front belt zone longitudinally distal from the central front belt zone towards the front waist edge, and a second peripheral front belt zone longitudinally proximal from the central front belt zone towards the leg opening, the central front belt zone having a first transverse peak extension force, the first peripheral front belt zone having a second transverse peak extension force, and the second peripheral front belt zone having a third transverse peak extension force, wherein the first transverse peak extension force is greater than one or both of the second and third transverse peak extension force, wherein the rear belt has a central rear belt zone, a first peripheral rear belt zone longitudinally distal from the central rear belt zone towards the rear waist edge and a second peripheral rear belt zone longitudinally proximal from the central rear belt zone towards the leg opening, the central rear belt zone having a fourth transverse peak extension force, the first peripheral rear belt zone having a fifth transverse peak extension force, and the second peripheral rear belt zone having a sixth transverse peak extension force, wherein the fourth transverse peak extension force is greater than one or both of the fifth and sixth transverse peak extension force, wherein the central front belt zone is provided at a second distance (L2) longitudinally offset from the front waist edge, and the central rear belt zone is provided at a first distance (L1) longitudinally offset from the rear waist edge, wherein the second distance (L2) is greater than the first distance (L1); wherein the elastic strands of the second peripheral front belt zone, and some or all of the elastic strands of the central front belt zone are severed to form discontinuous elastic strands with a first front belt segment disposed in a region towards the first longitudinal front belt side edge and a second front belt segment disposed in a region towards the second longitudinal front belt side edge, such that a region of the front belt between the first and second front belt segments, which overlaps the absorbent core of the central chassis, is free of elastic strands, and wherein at least the elastic strands of second peripheral rear belt zone are severed to form discontinuous elastic strands with a first rear belt segment disposed in a region towards the first longitudinal rear belt side edge and a second rear belt segment disposed in a region towards the second longitudinal rear belt side edge, such that a region of the rear belt between the first and second rear belt segments, which overlaps the absorbent core of the central chassis is free of elastic strands; and wherein, when the absorbent article is laid down to have the front and rear belt overlapping with each other and the front and rear waist edges coinciding, the central front belt zone and the central rear belt zone only partly overlap.
