1. An absorbent article comprising:

  • a front waist edge;

    a rear waist edge longitudinally opposing the front waist edge;

    a first side edge;

    a second side edge laterally opposing the first side edge;

    a longitudinal axis extending from a midpoint of the front waist edge to a midpoint of the rear waist edge;

    a lateral axis extending from a midpoint of the first side edge to a midpoint of the second side edge;

    a liquid permeable topsheet;

    a liquid impermeable backsheet;

    a pair of barrier leg cuffs extending at least partially between the front waist edge and the rear waist edge on opposite sides of the longitudinal axis, wherein each barrier leg cuff comprises;

    a proximal edge joined to the topsheet or the backsheet; and

    a free terminal edge; and

    an absorbent core disposed at least partially intermediate the topsheet and the backsheet and comprising a core wrap enclosing an absorbent material, wherein the core wrap comprises a first material and a second material, wherein the first material forms a C-wrap only partially around the second material, wherein the absorbent material comprises at least 80% of superabsorbent polymers by weight of the absorbent material, wherein the absorbent core comprises a first continuous channel substantially free of the superabsorbent polymers and at least partially oriented in the longitudinal direction of the article, wherein the absorbent core comprises a second continuous channel substantially free of the superabsorbent polymers and at least partially oriented in the longitudinal direction of the article, wherein the first and second channels each have lateral widths taken parallel to the lateral axis, wherein the absorbent core comprises a pocket that is substantially free of the superabsorbent polymers and that has a portion on the longitudinal axis, wherein the pocket has lateral widths taken parallel to the lateral axis, and wherein a profile of the sum of the lateral widths of the first and second channels and the lateral widths of the pocket over a longitudinal length of at least 50 mm taken along the longitudinal axis has two separate substantially constant portions.
