a backsheet;

an absorbent core disposed between the topsheet and the backsheet;

embossed central channels disposed in the central region;

a perimeter channel, wherein the outwardly convex transverse channels are disposed inboard of the perimeter channel;

a pair of rear channels disposed in the back end region and being disposed transversely inboard of the perimeter channel and longitudinally outboard of the outwardly convex longitudinal channels, wherein:

the pair of rear channels are disposed on opposite sides of a longitudinal axis,

the pair of rear channels are candy cane-shaped,

the pair of rear channels are inwardly convex, and

a transverse reinforcement channel joined to opposite sides of the perimeter channel, wherein the transverse reinforcement channel is disposed between the outwardly convex transverse channels and the rear channels.

2. The disposable absorbent article of claim 1 , wherein the absorbent core comprises absorbent fluff pulp and is absent of super absorbent polymer.

3. The disposable absorbent article of claim 1 , wherein the absorbent article has a dry bunch compression value of less than 6.0N.

4. The disposable absorbent article of claim 1 , wherein the perimeter channel further comprises a pair of inwardly convex longitudinal channels disposed inboard of the outwardly convex longitudinal channels.

5. The disposable absorbent article of claim 1 , further comprising a pair of front channels disposed in the front end region and being disposed transversely inboard of the perimeter channel.

6. The disposable absorbent article of claim 5 , wherein the pair of front channels are disposed on opposite sides of the longitudinal axis.

7. The disposable absorbent article of claim 5 , wherein the pair of front channels are disposed longitudinally outboard of the outwardly convex longitudinal channels.

8. The disposable absorbent article of claim 1 , wherein each of the embossed central channels comprises opposing sidewalls, a first portion forming a first bottom surface of the central channel, and a second portion forming a second bottom surface of the central channel, wherein the second bottom surface is subjacent the first bottom surface.

9. The disposable absorbent article of claim 8 , wherein the second portion is discrete and is surrounded by the first portion.

10. The disposable absorbent article of claim 9 , wherein the second portion does not contact either of the sidewalls of the embossed central channels.

11. The disposable absorbent article of claim 1 , wherein the perimeter channel, the pair of front channels, and the pair of rear channels each comprise opposing side walls, a first portion forming a first bottom surface of each of the perimeter channel, the pair of front channels and the pair of rear channels, and a second portion forming a second bottom surface of each of the perimeter channel, the pair of front channels and the pair of rear channels, wherein the second bottom surface is subjacent the first bottom surface.

12. The disposable absorbent article of claim 1 , wherein the perimeter channel is continuous.

13. The disposable absorbent article of claim 1 , wherein the perimeter channel extends from the front end region to the back end region.

14. The disposable absorbent article of claim 1 , wherein the embossed central channels comprise outwardly convex transverse channels and outwardly convex longitudinal channels, wherein the outwardly convex transverse channels and the outwardly convex longitudinal channels are joined together.
