Claim:
1. An absorbent article, the absorbent article having a front edge, a back edge, a front region, a back region, a crotch region, and a longitudinal axis extending in a longitudinal direction of the article, the article having a length L of at least about 320 mm as measured along the longitudinal axis from the front edge to the back edge, the absorbent article comprising: a liquid permeable topsheet; a liquid impermeable backsheet; an absorbent core disposed between the topsheet and backsheet, the absorbent core comprising a core wrap enclosing an absorbent material, wherein the absorbent material comprises at least about 80% of superabsorbent polymers by weight of the absorbent material, and wherein the absorbent core comprises at least a pair of channels symmetrically disposed relative to the longitudinal axis of the core and spaced apart by a minimum spacing distance of at least 10 mm throughout their whole longitudinal dimension, wherein the channels have a length projected on the longitudinal axis of the core which is at least 10% of the length L of the absorbent core, wherein the channels are substantially free of the absorbent material, wherein the width of a portion of the channels is at least about 2 mm, wherein the core wrap comprises a top side and a bottom side, and wherein the top side and the bottom side are bonded directly to each other through at least a portion of the channels; wherein the absorbent core comprises no channels at the longitudinal axis; wherein the channels are present at least at the same longitudinal level as a crotch point, C, wherein the crotch point is defined as the point placed at a distance of two fifths of L from the front edge of the absorbent article on the longitudinal axis, and wherein the channels extend from the crotch region into the back region; wherein the absorbent core comprises a first absorbent layer and a second absorbent layer, wherein the first absorbent layer comprises a first substrate and a first layer of superabsorbent polymers, wherein the second absorbent layer comprises a second substrate and a second layer of superabsorbent polymers, wherein the absorbent core comprises a fibrous thermoplastic adhesive material at least partially bonding the layers of superabsorbent polymer to their respective substrates, and wherein the first substrate and the second substrate form the top and bottom layers of the core wrap; and an acquisition-distribution system between the topsheet and the absorbent core, the acquisition-distribution system comprising one or more layers, wherein the acquisition-distribution system does not comprise a layer comprising at least about 50% by weight of synthetic fibers and having a basis weight above about 150 gsm.
