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.

7. 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.

8. The disposable absorbent article of claim 7 , wherein the pair of front channels are disposed on opposite sides of a longitudinal axis.

9. 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.
