WHAT IS CLAIMED IS:

1. An absorbent article comprising :

an absorbent body;

an outer cover; and

a fluid-entangled nonwoven material, the absorbent body being disposed between the fluid- entangled nonwoven material and the outer cover, the fluid-entangled nonwoven material comprising:

a first surface and a second surface, the first surface being opposite from the second surface;

a plurality of nodes extending away from a base plane on the first surface towards the absorbent body; and

a plurality of openings extending from the first surface to the second surface through the fluid-entangled nonwoven material, individual openings of the plurality of openings being disposed between adjacent nodes of the plurality of nodes.

2. The absorbent article of claim 1 , wherein the plurality of nodes do not include any openings.

3. The absorbent article of claim 1 , wherein the fluid-entangled nonwoven material further comprises a plurality of connecting ligaments interconnecting the plurality of nodes.

4. The absorbent article of claim 3, wherein the plurality of nodes, the plurality of openings, and the plurality of connecting ligaments are disposed in an apertured zone of the fluid-entangled nonwoven material, and wherein the fluid-entangled nonwoven material further comprises a pair of side zones including a first side zone and a second side zone, the first side zone being adjacent to a first side of the apertured zone and the second side zone being adjacent to a second side of the apertured zone.

5. The absorbent article of claim 1 , wherein the fluid-entangled nonwoven material provides a

compression energy of at least about 40 gf*cm in any cycle of the Compression Energy T est Method.

6. The absorbent article of claim 1 , wherein the fluid-entangled nonwoven material provides a

percent open area in an apertured zone of the fluid-entangled nonwoven material from about 10% to about 60% as determined by the Material Sample Analysis Test Method.

7. The absorbent article of claim 1 , wherein a majority of the plurality of nodes each comprise a height of between about 1 mm to about 10mm.

8. The absorbent article of claim 1 , wherein the plurality of nodes provide a node density of about 1.0 nodes/cm2 to about 3.0 nodes/cm2 in an apertured zone of the fluid-entangled nonwoven material.

9. The absorbent article of claim 1 , wherein the fluid-entangled nonwoven material provides at least a portion of a body facing surface of the absorbent article.

10. An absorbent article comprising:

an absorbent body;

an outer cover; and

a fluid-entangled nonwoven material, the absorbent body being disposed between the fluid- entangled nonwoven material and the outer cover, the fluid-entangled nonwoven material comprising:

a first surface and a second surface, the first surface being opposite from the second surface;

a plurality of nodes extending away from a base plane on the first surface towards the absorbent body;

a plurality of connecting ligaments interconnecting the plurality of nodes; and a plurality of openings, the plurality of openings being formed between the plurality of connecting ligaments and the plurality of nodes.

11. The absorbent article of claim 10, wherein a plurality of nodes do not include any openings.

12. The absorbent article of claim 10, wherein the plurality of nodes, the plurality of openings, and the plurality of connecting ligaments are disposed in an apertured zone of the fluid-entangled nonwoven material, and wherein the fluid-entangled nonwoven material further comprises a pair of side zones including a first side zone and a second side zone, the first side zone being adjacent to a first side of the apertured zone and the second side zone being adjacent to a second side of the apertured zone.

13. The absorbent article of claim 10, wherein the fluid-entangled nonwoven material provides a compression energy of at least about 40 gf*cm in any cycle of the Compression Energy T est Method.

14. The absorbent article of claim 10, wherein the fluid-entangled nonwoven material provides a percent open area in an apertured zone of the fluid-entangled nonwoven material from about 10% to about 60% as determined by the Material Sample Analysis Test Method.

15. The absorbent article of claim 10, wherein a majority of the plurality of nodes each comprise a height of between about 1 mm to about 10mm.

16. The absorbent article of claim 10, wherein the plurality of nodes provide a node density of about 1.0 nodes/cm2 to about 3.0 nodes/cm2 in an apertured zone of the fluid-entangled nonwoven material.

17. The absorbent article of claim 10, wherein the fluid-entangled nonwoven material provides at least a portion of a body facing surface of the absorbent article.

18. An absorbent article comprising:

an absorbent body;

an outer cover; and

a fluid-entangled nonwoven material, the absorbent body being disposed between the fluid- entangled nonwoven material and the outer cover, the fluid-entangled nonwoven material comprising:

a first surface and a second surface, the first surface being opposite from the second surface;

a plurality of nodes extending away from a base plane on the first surface towards the absorbent body;

a plurality of connecting ligaments interconnecting the plurality of nodes, each individual connecting ligament of the plurality of connecting ligaments extending between adjacent nodes of the plurality of nodes; and

a plurality of openings, each of the plurality of openings being defined between at least three connecting ligaments of the plurality of connecting ligaments and at least three nodes of the plurality of nodes.

19. The absorbent article of claim 18, further comprising a bodyside liner, the bodyside liner being disposed between the fluid-entangled nonwoven material and the absorbent body.

20. The absorbent article of claim 19, wherein a width of the fluid-entangled nonwoven material is less than a width of the bodyside liner.
