2 . The product of claim 1 wherein the Compression Slope is from about 12 to about 25.

3 . The product of claim 1 wherein the basis weight is from 27 lbs/3000 ft 2 to about 40 lbs/3000 ft 2 .

4 . The product of claim 3 wherein the basis weight is from 30 lbs/3000 ft 2 and about 40 lbs/3000 ft 2 .

5 . The product of claim 1 wherein the Flex Modulus is from about 0.2 to about 0.75.

6 . The product of claim 5 wherein the Flex Modulus is from about 0.3 to about 0.7.

7 . The product of claim 1 wherein at least one of the plies comprises a plurality of domes formed during the papermaking process wherein the ply comprises from about 10 to about 1000 domes per square inch of the ply.

8 . The product of claim 7 wherein the ply comprises from about 50 to about 300 domes per square inch of the ply.

9 . The product of claim 7 wherein the fibrous substrate comprises from about 8% to about 60% of eucalyptus fibers.

10 . The product of claim 1 wherein the Wet Caliper is from about 22 mils to about 35 mils.

11 . The product of claim 10 wherein the Wet Caliper is from about 28 mils to about 30 mils.

12 . The product of claim 7 further comprising a sheet caliper of at least about 29 mils.

13 . The product of claim 12 wherein the sheet caliper is from about 30 mils to about 50 mils.

14 . The product of claim 13 wherein the sheet caliper of from about 33 mils to about 45 mils.

15 . The product of claim 1 wherein the fibrous structure product further comprises a chemical softening agent at a level from about 0.05 lbs/ton to about 6 lbs/ton, of furnish.

16 . The product of claim 15 wherein the chemical softening agent is selected from the group consisting of quaternary ammonium compounds, organo-reactive polydimethyl siloxane compounds, and mixtures thereof.

17 . The product of claim 16 wherein the chemical softening compound is selected from the group consisting of dialkyldimethylammonium salts, ditallowedimethylammonium chloride, ditallowedimethylammonium methyl sulfate, di(hydrogenated tallow)dimethyl ammonium chloride, mono or diester variations of the dialkyldimethylammonium, and mixtures thereof.

18 . The product of claim 7 wherein at least one of the plies is selected from the group consisting of: creped or uncreped through-air-dried fibrous structure plies, differential density fibrous structure plies, wet laid fibrous structure plies, air laid fibrous structure plies, conventional fibrous structure plies and mixtures thereof.

19 . The product of claim 18 wherein the ply comprises a creped through-air dried paper.

20 . The product of claim 1 wherein at least one of the plies has a plurality of embossments.

21 . The product of claim 1 wherein only one of the plies has a plurality of embossments.

22 . The product of claim 1 wherein the product is two ply wherein both plies comprise a plurality of embossments.

23 . A fibrous structure product comprising:

one ply of fibrous structure wherein the fibrous structure has a Compression Slope from about 11 to about 30; a basis weight from about 28 lbs/3000 ft 2 to about 50 lbs/3000 ft 2 ; a Wet Caliper from about 18 mils to about 40 mils; and a Flex Modulus from about 0.1 to about 0.8.

24 . The product of claim 23 wherein the Compression Slope is from about 12 to about 25.

25 . The product of claim 23 wherein the basis weight is from 27 lbs/3000 ft 2 to about 40 lbs/3000 ft 2 .

27 . The product of claim 23 wherein the Flex Modulus is from about 0.2 to about 0.75.

28 . The product of claim 27 wherein the Flex Modulus is from about 0.3 to about 0.7.

29 . The product of claim 23 comprising a plurality of domes formed during the papermaking process wherein the ply comprises from about 10 to about 1000 domes per square inch of the ply.

30 . The product of claim 29 wherein the ply comprises from about 50 to about 300 domes per square inch of the ply.

31 . The product of claim 23 wherein the fibrous substrate comprises from about 8% to about 60% of eucalyptus fibers.

32 . The product of claim 23 wherein the Wet Caliper is from about 22 mils to about 35 mils.

33 . The product of claim 32 wherein the Wet Caliper is from about 28 mils to about 30 mils.

34 . The product of claim 23 further comprising a sheet caliper of at least about 29 mils.
