The absorbent article of claim 1, wherein the liquid management system comprises a first layer and a second layer, wherein the first layer is positioned adjacent to the liquid permeable material, and wherein the second layer is positioned adjacent to the core wrap. 3. The absorbent article of claim 2, wherein the first layer or the second layer comprises a nonwoven material. 4. The absorbent article of claim 2, wherein the first or the second layer comprises cross-linked cellulose fibers. 5. The absorbent article of claim 1, wherein the liquid management system comprises an open-celled foam. 6. The absorbent article of claim 1, wherein the liquid management system comprises air-laid fibers. 7. The absorbent article of claim 1, wherein at least a portion of the first channel overlaps at least a portion of the second channel. 8. The absorbent article of claim 2, wherein a portion of the first layer or the second layer of the liquid management system has a different color than the liquid permeable material or a portion of the absorbent core. 9. The absorbent article of claim 1, wherein bodily exudate is at least partially visible through the liquid impermeable material when the bodily exudate is within or proximate to the first and second channels. 10. The absorbent article of claim 1, wherein the absorbent core periphery defines a generally hour-glass shape. 11. The absorbent article of claim 1, comprising an indicator configured to transition from a first state to a second state when bodily exudate is within the first or the second channel. 12. The absorbent article of claim 1, wherein the absorbent core comprises: a first material of the core wrap;a first layer of the superabsorbent polymers;a second material of the core wrap;a second layer of the superabsorbent polymers; anda fibrous thermoplastic adhesive material at least partially bonding the first material to the first layer of the superabsorbent polymers and the second material to the second layer of the superabsorbent polymers, wherein the first channel extends substantially through the thickness of the first layer of superabsorbent polymers and substantially through the thickness of the second layer of superabsorbent polymers. 13. The absorbent article of claim 1, wherein the liquid permeable material defines a plurality of apertures and forms a topsheet of the absorbent article. 14. The absorbent article of claim 1, wherein the liquid management system comprises a plurality of layers, and wherein one of the layers comprises a carded, resin bonded nonwoven material. 15. The absorbent article of claim 1, wherein the second channel is at least partially aligned with a visual element on the liquid permeable material, or the liquid impermeable material. 16. The absorbent article of claim 1, comprising a liquid distribution material, wherein the liquid distribution material overlaps a lateral axis of the absorbent article, and wherein the basis weight of the absorbent material in a portion of the absorbent core that overlaps, directly or indirectly, the liquid distribution material is at least 25% greater than the basis weight of non-overlapping portions of the absorbent material. 17. The absorbent article of claim 1, wherein the first channel has a longitudinal length, wherein the first channel has an average lateral width over the longitudinal length, and wherein the average lateral width over the longitudinal length is substantially constant. 18. The absorbent article of claim 1, wherein the second channel has a longitudinal length, wherein the second channel has an average lateral width over the longitudinal length, and wherein the average lateral width over the longitudinal length is substantially constant. 19. An absorbent article comprising: a central longitudinal axis;a longitudinal length extending 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 longitudinal length of the absorbent article;a liquid permeable material;a liquid impermeable material;an absorbent core disposed at least partially intermediate the liquid permeable material and the liquid impermeable material and comprising an absorbent material, wherein the absorbent material is positioned within a core wrap, wherein the core wrap forms a C-wrap, wherein the absorbent material comprises at least 85% of superabsorbent polymers by weight of the absorbent material, wherein the absorbent core defines a first channel substantially free of the superabsorbent polymers, wherein the first channel extends into the front waist region, and wherein the first channel extends substantially through the thickness of the absorbent material and that is free of overlap with the central longitudinal axis; anda liquid management system comprising a first layer and a second layer, wherein the first layer is positioned at least partially intermediate the liquid permeable material and the second layer, and wherein the second layer is positioned at least partially intermediate the first layer and the core wrap, wherein the first or second layer defines a second channel that is free of overlap with the central longitudinal axis, wherein the liquid management system is substantially free of any superabsorbent polymers, and wherein the second channel extends into the front waist region. 20.
