1. An absorbent article having a skin facing side, a garment facing side, a longitudinal axis, a transverse axis, a pair of longitudinally extending side edges, and a pair of transversely extending end edges, the absorbent article comprising an absorbent body, a front belt joined to the front side of the absorbent body, a back belt joined to the back side of the absorbent body, and the transverse edges of the front belt and the back belt are joined by a seam to form a waist opening and two leg openings,
each front belt and back belt formed by a plurality of elastic bodies running in the transverse direction sandwiched between an inner sheet and an outer sheet;
the absorbent body comprising:
a core chassis comprising:
a liquid permeable topsheet;
a liquid impermeable backsheet;
an absorbent core disposed between the topsheet and the backsheet, the absorbent core having a smaller dimension than the backsheet in both the longitudinal direction and the transverse direction;
an outer cover disposed on a garment facing side of the backsheet, the outer cover having a greater dimension than the absorbent core in the transverse direction, and the same or smaller dimension than the backsheet in both the longitudinal direction and the transverse direction; and
a pair of core side regions defined as the region between absorbent core side edges and the backsheet side edges; and
a leg gasketing system made by a pair of water impermeable cuff material disposed laterally outside and wrapping the pair of sides edges of the core chassis, the leg gasketing system comprising:
a pair of wearer facing cuff regions formed by inwardly extending the cuff material over a wearer facing side of the core chassis; each of the pair of wearer facing cuff regions comprise a longitudinally extending inner cuff sealing and a longitudinally extending inner cuff free edge positioned inward from the inner cuff sealing, wherein the inner cuff sealing bonds the cuff material and the topsheet, and an inner cuff elastic element is disposed adjacent the inner cuff free edge;
a pair of garment facing cuff regions formed by inwardly extending the cuff material over a garment facing side of the core chassis, and
a pair of outer cuff elastic elements disposed on the garment facing cuff regions, each outer cuff elastic element disposed so as to superpose the core side regions and so as to superpose the inner cuff sealings or outward thereof; and
wherein the garment facing cuff regions are formed by the cuff material extending inwardly from a first fold line to define a first cuff garment facing fold and the cuff material extending outwardly from a second fold line to define a second cuff garment facing fold;
wherein the outer cuff elastic element is sandwiched between the first garment facing fold and the second garment facing fold; and
wherein the second cuff garment facing fold is sandwiched between the outer cuff elastic element and the garment facing side of the core chassis; and
wherein the absorbent article has a Worn Leg Opening (WLO) of from 300 mm to 450 mm, a Minimum Leg Opening (MLO) of from 225 mm to 300 mm, and a ratio of WLO/MLO of from 1.5 to 1.7.
