An absorbent article continuous in a longitudinal direction and a transverse direction comprising a front elastic belt region, a back elastic belt region, a crotch region, a waist opening and two leg openings; the front and back elastic belt regions (84, 86) being 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 front and back elastic belt regions (84, 86) in the transverse direction, the outer sheet having a material caliper of at least 0.25mm at 500Pa; the article further comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet; the absorbent core existing through the entire longitudinal dimension of the crotch region and extending at least partly in the back elastic belt region; the back elastic belt region having a maximum caliper, MaxBC, and a minimum caliper, MinBC, according to the measurements herein, wherein the difference between the MaxBC and the MinBC is no greater than 5mm, wherein the ratio of the MaxBC to the MinBC is no greater than 2.2; and wherein the MaxBC is no greater than 8 mm; and wherein the back elastic belt region has a maximum caliper delta, ΔMaxBC, of no greater than 7 mm, according to the measurements herein; wherein the article comprises a core chassis and a ring-like elastic belt comprising a front belt and a back belt; the center of the front belt is joined to a front waist panel of the core chassis, the center of the back belt is joined to a back waist panel of the core chassis, and the remainder of the core chassis forms the crotch region, the front and back belt each having a left side panel and a right side panel where the core chassis does not overlap, 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; wherein the front belt and the back belt are discontinuous of each other in the longitudinal direction; wherein the front belt and the back belt forms the elastic belt region; wherein the core chassis comprises the outer cover layer at the most garment-facing side and a backsheet attached to the body-facing surface of the outer cover layer; wherein the longitudinal length of the outer cover layer is longer than the longitudinal length of the crotch region and shorter than the longitudinal length of the backsheet, the area on the front waist panel or the back waist panel where the outer cover layer is present forming a transitional region; and wherein the outer sheet is an air-through carded nonwoven made of crimping fiber made through core eccentric bicomponent filament, or side by side bicomponent filament; and wherein the absorbent core comprises an absorbent layer which is substantially cellulose free. the front and back elastic belt regions (84, 86) being 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 front and back elastic belt regions (84, 86) in the transverse direction, the outer sheet having a material caliper of at least 0.25mm at 500Pa;
