Bottles with improved top loading resistance are disclosed herein. The bottles may have generally “square” body profiles and may include structural features such as variable wall thickness, specific shoulder angles, and other structural reinforcement components. The bottles may include laterally extending ribs on the barrel to improve their lateral stacking strength, and may do so without adversely affecting their top loading strength. The bottles may have one or both of the following characteristics: a weight and barrel thickness specific top loading strength of no less than 2.30 lbf/g×mm and a weight and volume specific top loading strength of no less than 1.00 lbf×L/g.
