An absorbent article for personal hygiene such as a diaper or training pant, the absorbent article having a front edge and a back edge, a longitudinal axis extending in a longitudinal direction of the article, the article having a length L as measured along the longitudinal axis from the front edge to the back edge, a crotch point defined as the point placed at a distance of two fifth of L from the front edge of the article on the longitudinal axis, the absorbent article comprising: - a liquid permeable topsheet, - a liquid impermeable backsheet, - a pair of barrier leg cuffs extending at least partially between the front edge and the back edge of the diaper on opposite sides of the longitudinal axis and present at least at the longitudinal position of the crotch point, each barrier leg cuff being delimited by a proximal edge joined directly or indirectly to the topsheet and/or the backsheet and a free terminal edge, - an absorbent core between the topsheet and backsheet and comprising a core wrap comprising at least two substrates (16, 16') being attached to each other and enclosing an absorbent material, wherein the absorbent material comprises at least 80% of superabsorbent polymers ("SAP") by weight of the absorbent material, wherein the absorbent core comprises from 5 g to 60 g of SAP; - wherein the absorbent core comprises at least a pair of channels (26, 26') at least partially oriented in the longitudinal direction of the article, - wherein the core wrap comprises a top side and a bottom side and the top side and the bottom side are bonded to each other through at least a portion of the channels, and wherein the article has a Relative Crotch Width Reduction (RCWR) of from 32 mm/kg to 150 mm/kg, wherein the RCWR is calculated according to the formula: RCWR ≡ Wd − Ww Mw − Md wherein Wd is the dry crotch width and Ww is the wet crotch width at the crotch point, and Mw is the wet mass of the article and Md is the dry mass of the article, the measurements being made as indicated according to RCWR Test described herein, wherein the article has a dry crotch width Wd of from to 70 mm to 200 mm; and wherein the core wrap is at least partially sealed along all the sides of the absorbent core so that less than 5% by weight of absorbent material escapes the core while performing the RCWR test. - a liquid permeable topsheet, - a liquid impermeable backsheet, - a pair of barrier leg cuffs extending at least partially between the front edge and the back edge of the diaper on opposite sides of the longitudinal axis and present at least at the longitudinal position of the crotch point, each barrier leg cuff being delimited by a proximal edge joined directly or indirectly to the topsheet and/or the backsheet and a free terminal edge, - an absorbent core between the topsheet and backsheet and comprising a core wrap comprising at least two substrates (16, 16') being attached to each other and enclosing an absorbent material, wherein the absorbent material comprises at least 80% of superabsorbent polymers ("SAP") by weight of the absorbent material, wherein the absorbent core comprises from 5 g to 60 g of SAP; - wherein the absorbent core comprises at least a pair of channels (26, 26') at least partially oriented in the longitudinal direction of the article, - wherein the core wrap comprises a top side and a bottom side and the top side and the bottom side are bonded to each other through at least a portion of the channels, and
