13. The container of claim 1 , wherein the at least one horizontal body rib has a depth between 3% and 5% of a width of the first and second side walls.

14. The container of claim 1 , wherein the at least one horizontal body rib is formed in the front wall.

15. The container of claim 14 , wherein the at least one horizontal body rib extends from the front wall about rounded corners disposed between the front wall and the first and second side walls, respectively.

16. The container of claim 14 , wherein the at least one horizontal body rib comprises a plurality of horizontal body ribs.

17. The container of claim 16 , wherein the plurality of horizontal body ribs comprises four horizontal body ribs.

18. The container of claim 16 , wherein each of the plurality of horizontal body ribs are spaced vertically an equal distance from each adjacent horizontal body rib.

19. The container of claim 16 , wherein the plurality of horizontal body ribs are spaced vertically an equal distance from the first and second circumferential ribs.

20. The container of claim 14 , further comprising at least one opposing horizontal body rib formed in the rear wall.

21. The container of claim 20 , wherein the at least one horizontal body rib comprises a plurality of horizontal body ribs and the at least one opposing horizontal body rib comprises a plurality of opposing horizontal body ribs.

22. The container of claim 21 , wherein the plurality of horizontal body ribs comprises four horizontal body ribs and the plurality of horizontal opposing horizontal body ribs comprises four opposing horizontal body ribs.

23. The container of claim 1 , wherein only one vertical strut is formed in the front sidewall and only one vertical strut is formed in the second side wall, each vertical strut is disposed between a corresponding one of the first and second grip areas and the at least one horizontal body rib.

24. The container of claim 1 , wherein each vertical strut has a depth between 2% and 5% of a width of the first and second side walls.

25. The container of claim 1 , wherein each vertical strut has a varied width along its length.

26. The container of claim 1 , wherein the container comprises polyethylene terephthalate.

27. The container of claim 1 , wherein the container has a volume of about 59 ounces formed from a preform having a mass of about 58 grams.

28. A container comprising:

a top portion comprising a finish portion;

a body portion disposed below the top portion; and

a bottom portion disposed below the body portion opposite the top portion;

the body portion comprising:

a front wall,

a rear wall opposite the front wall,

first and second side walls extending between the front wall and the rear wall to define a generally rectangular shape in plan view, the first side wall disposed opposite the second side wall,

opposing grip areas formed in the first and second side walls, the opposing grip areas including a first grip area formed in the first side wall and a second grip area formed in the second side wall,
