A disposable hygiene article having an absorbent core with a first region which has its narrowest width (M) in the transverse direction (x) in a front portion or at a location of a transition between the front portion and a crotch portion of the article. The absorbent core comprises a high-density first region and a low density second region. The absorbent core in the crotch region has first and second rear compression lines. The compression lines mutually diverge in a direction towards the core front edge. Each line has a diverging angle (α2; α3) of from 15-60° with respect to a centre line (A). The second region has an average density which is at least 20% lower than the average density of the first region.
A disposable hygiene article, wherein said article has a transverse direction (x), a longitudinal direction (y) and a longitudinal centre line (A) dividing the article into two mutually symmetrical and mirror-imaged portions (I) and (II), wherein said article has a front portion, a crotch portion and a rear portion, and said article comprises a liquid-permeable topsheet, a liquid-impermeable backsheet, an absorbent core arranged between the topsheet and backsheet, and optionally a liquid acquisition sheet arranged between the topsheet and the core, wherein an outer contour of the absorbent core is defined by mirror-imaged first and second core edge lines, and the core is delimited by a core front edge in the front portion and a core rear edge in the rear portion, wherein said absorbent core comprises a first region extending in the longitudinal direction (y) of the article from a first region front edge in the front portion over the crotch portion to the rear portion, and wherein the outer contour of the first region is defined by mirror-imaged first and second first region edge lines, and wherein said first region comprises a head part and two leg portions extending symmetrically about the centre line (A) and in a longitudinal direction (y) of the article, starting and diverging from a common leg portion start point (a0) in the crotch portion and extending over a portion of the crotch portion towards separate leg portion endings in the rear portion, wherein a distance (ax) between facing sides of the respective leg portions in the transverse direction (x) varies in the longitudinal direction (y), whereby a maximum distance (a1) between the facing sides of the respective leg portions in the transverse direction (x) is in the crotch portion, located at a position in the longitudinal direction (y) corresponding to a position of a crotch point, wherein said facing sides of the respective leg portions converge backwards in the longitudinal direction (y) such that said distance (ax) is reduced from said maximum distance (a1) to a minimum distance (a2), wherein said absorbent core further comprises a second region at least partially surrounded by said first region and extending between said leg portions in the transverse direction (x) and in the length direction (y) from the leg portion start point (a0) in the crotch portion to an end point (al) in the rear portion wherein:
