A blow molded plastic hot-fill container includes at least one vacuum panel for inward flexure under vacuum after the container is hot-filled and capped. The vacuum panel is externally concave as viewed in cross section from a first direction and externally convex as viewed in cross section from a second direction orthogonal to the first direction. The at least one vacuum panel preferably is disposed in a sidewall of the container, which preferably is of generally uniform wall thickness, and preferably includes an array of vacuum panels angularly spaced around an axis of the container.
