What is claimed is: 1. An absorbent article comprising: a front waist region, a back waist region, and a crotch region extending between the waist regions, a first ear panel formed of a first material extending from a first edge portion of the front waist region; a second ear panel formed of a second material different from the first material extending from a first edge portion of the back waist region, the second material having a basis weight greater than a basis weight of the first material; and at least one manually tearable passive bond connecting the first ear panel and the second ear panel together. 2. The absorbent article of claim 1 wherein the second material has a basis weight of at least about 20 gsm. 3. The absorbent article of claim 1 wherein the first material has a basis weight of less than about 20 gsm. 4. The absorbent article of claim 1 wherein the second material has a basis weight of at least about 30 gsm. 5. The absorbent article of claim 1 wherein the first material and the second material each has a basis weight of at least about 20 gsm. 6. The absorbent article of claim 1 wherein the first material and the second material each has a basis weight of about 30 gsm to about 60 gsm. 7. The absorbent article of claim 1 wherein the second material has a peak load grab tensile strength of about 8.5 lbs. to about 100 lbs. 8. The absorbent article of claim 1 wherein the first ear panel is passively bonded to the second ear panel by one of sonic welding, adhesive bonding, thermal bonding and combinations thereof. 9. The absorbent article of claim 1 wherein the first material comprises a point bonded nonwoven material. 10. The absorbent article of claim 1 wherein the second material comprises a laminate having at least one film layer positioned between two layers of polypropylene spunbond material. 11.
