A hot fill type plastic container includes a bottom, a finish portion and a main body portion. The main body portion has a maximum outer diameter and a sidewall having an outer surface. A sidewall has a plurality of helical vacuum panels defined therein. Each of the helical vacuum panels has a depth that is substantially within a range of about 1.7% to about 4.5% of the maximum outer diameter of the main body portion. In addition, each of the helical vacuum panels has an upper portion having a first maximum width and a lower portion having a second maximum width, with the second maximum width being greater than the first maximum width. The upper portion of each of the vacuum panels further has a first helical pitch that is greater than a second helical pitch of the lower portion.
