6. The absorbent article of claim 1 , wherein the first channel is free from overlap with the central longitudinal axis.
7. The absorbent article of claim 6 , wherein the absorbent core comprises a third channel substantially free of the superabsorbent polymers, and wherein the third channel is free from overlap with the central longitudinal axis.
8. The absorbent article of claim 7 , wherein the first channel is positioned on a first side of the central longitudinal axis, and wherein the third channel is positioned on a second side of the central longitudinal axis.
9. The absorbent article of claim 1 , wherein the liquid permeable topsheet defines a plurality of apertures.
10. The absorbent article of claim 1 , wherein the liquid management system defines a third channel therethrough, wherein the second channel is positioned on a first side of the central longitudinal axis, and wherein the third channel is positioned on a second side of the central longitudinal axis and is substantially material free.
11. The absorbent article of claim 1 , wherein a portion of the liquid impermeable backsheet is joined to the portion of the liquid permeable topsheet within the second channel.
12. The absorbent article of claim 1 , wherein the liquid management system comprises more than one layer, and wherein one of the layers comprises cross-linked cellulose fibers.
13. An absorbent article comprising:
a central longitudinal axis;
a liquid permeable topsheet forming a portion of a wearer-facing surface of the absorbent article;
a liquid impermeable backsheet;
an absorbent core disposed at least partially intermediate the liquid permeable topsheet and the liquid impermeable backsheet and comprising an absorbent material, wherein the absorbent material is positioned within a core wrap, wherein the absorbent material comprises at least 85% of superabsorbent polymers by weight of the absorbent material, and wherein the absorbent core defines a first channel substantially free of the superabsorbent polymers and that is free from overlap with the central longitudinal axis;
a first material positioned at least partially intermediate the liquid permeable topsheet and the core wrap, wherein the first material is substantially free of any superabsorbent polymers; and
a second material positioned at least partially intermediate the first material and the core wrap, wherein the second material is substantially free of any superabsorbent polymers, wherein the second material defines a second channel therethrough that is free from overlap with the central longitudinal axis, and wherein the second channel is substantially material free;
wherein a portion of the first material is recessed into the second channel.
14. The absorbent article of claim 13 , wherein the portion of the first material is recessed into the first channel.
15. The absorbent article of claim 13 , wherein the first channel substantially overlaps the second channel.
16. The absorbent article of claim 13 , wherein the first material has a first color and the second material has a second color, and wherein the first color and the second color are different.
17. The absorbent article of claim 13 , wherein a portion of the liquid permeable topsheet is recessed into the second channel.
18. The absorbent article of claim 13 , wherein a portion of the liquid impermeable backsheet is recessed into the first channel.
19. The absorbent article of claim 13 , wherein the second material comprises cross-linked cellulose fibers.
20. The absorbent article of claim 13 , wherein the second material comprises wet-laid cellulosic material.
21. The absorbent article of claim 13 , wherein the first material comprises a carded, resin bonded, nonwoven material.
22. The absorbent article of claim 13 , wherein the first material is at least partially joined to the liquid impermeable backsheet within the first or second channel.
23. An absorbent article comprising:
a central longitudinal axis;
a total longitudinal length extending in a direction parallel to the central longitudinal axis;
a front waist region;
a rear waist region;
a crotch region positioned intermediate the front waist region and the rear waist region, wherein the front waist region, the rear waist region, and the crotch region each define ⅓ of the total longitudinal length of the absorbent article;
a liquid permeable topsheet forming a portion of a wearer-facing surface of the absorbent article;
