1. A pant-type absorbent article defining a longitudinal direction and a transverse direction orthogonal to the longitudinal direction, the absorbent article comprising:
a chassis;
a topsheet;
a backsheet; and
an absorbent member arranged between the topsheet and the backsheet,
wherein the absorbent member has an absorbent member front edge and an absorbent member rear edge,
wherein the chassis comprises a front section, a rear section and a crotch section located between the front section and the rear section, as seen in the longitudinal direction of the absorbent article,
wherein the front section and the rear section are joined to each other along respective opposite longitudinal side edges thereof to define a waist-opening and a pair of leg-openings,
wherein the front section comprises front elastics and the rear section comprises rear elastics,
wherein each of the front elastics and the rear elastics extend between the respective opposite longitudinal side edges in the transverse direction (T) of the absorbent article,
wherein the absorbent member comprises a first absorbent layer and a second absorbent layer,
wherein the first absorbent layer is arranged between the topsheet and the second absorbent layer,
wherein the first absorbent layer has a first absorbent layer front edge and a first absorbent layer rear edge,
wherein the second absorbent layer has a size and a shape in a plane of the absorbent article that define the size and shape of the absorbent member in the plane of the absorbent article,
wherein the first absorbent layer is shorter than the second absorbent layer, as seen in the longitudinal direction, such that only the second absorbent layer is present in a front portion and a rear portion of the absorbent member,
wherein the front elastics extend over the front portion of the absorbent member and the rear elastics extend over the rear portion of the absorbent member,
wherein the first absorbent layer front edge is arranged with a front edge distance (d1) from the absorbent member front edge and the first absorbent layer rear edge is arranged with a rear edge distance (d2) from the absorbent member rear edge,
wherein each of the first and the second absorbent layer comprises superabsorbent polymer particles,
wherein the absorbent member in a crotch portion thereof is provided with at least two channels extending in the longitudinal direction and on a respective side of a longitudinal centerline of the absorbent article,
wherein the first absorbent layer comprises a higher amount of superabsorbent polymer particles than the second absorbent layer, the absorbent member having a total absorbent capacity of 1100 ml or more, as measured according to standard test method ISO 11948-1, and
wherein a ratio between the front edge distance (d1) and the rear edge distance (d2) is 1.5 or greater.
