1. A wearable article continuous in a longitudinal direction and a transverse direction, comprising:
an elastic belt region, a crotch region, a waist opening and two leg openings;
wherein the elastic belt region is a laminate comprising an inner sheet made of nonwoven fiber, and an outer sheet made of nonwoven fiber, and a plurality of elastic bodies configured to stretch the elastic belt region in the transverse direction, wherein the outer sheet is a 20-50 gsm air-through carded nonwoven made of crimping fiber made through core eccentric bicomponent filament or side by side bicomponent filament;
wherein the crotch region comprises an outer cover layer at a most garment facing side, the outer cover layer being the same material as the outer sheet;
wherein the outer sheet has a Compression Work of at least about 550 gfmm, a Compression Average Rigidity of less than about 500 gf/mm3, a Surface Roughness Wavelength of at least about 1.7 mm, and a Glossiness of less than about 5.3; and
a central chassis and a ring-like elastic belt comprising a front belt and a back belt;
wherein a center of the front belt is joined to a front waist panel of the central chassis, a center of the back belt is joined to a back waist panel of the central chassis, and a remainder of the central chassis forms the crotch region, the front and back belt each having a left side panel and a right side panel where the central chassis does not overlap, and transverse edges of the front belt and the back belt are joined by a seam to form a waist opening and two leg openings; wherein the front belt and the back belt are discontinuous of each other in the longitudinal direction; and
wherein the front belt and the back belt form the elastic belt region;
wherein the central chassis comprises a backsheet attached to the wearer facing surface of the outer cover layer; wherein a longitudinal length of the outer cover layer is longer than a longitudinal length of the crotch region and shorter than a longitudinal length of the backsheet, an area on the front waist panel or the back waist panel where the outer cover layer is present defines a transitional region, and wherein the longitudinal length of the transitional region is no more than about 10 mm, and wherein adhesive is applied to the transitional region for a longitudinal length that is less than the longitudinal length of the transitional region.
