The present disclosure provides a reversibly foldable freight container having a roof structure, a floor structure and sidewall structures. The reversibly foldable freight container further includes a front wall and a rear wall, where the front wall includes front wall corner posts, a front door hinge on at least one of the front wall corner posts and a front door joined to the front door hinge. The rear wall includes rear wall corner posts, a hinge on the rear wall corner posts and a rear wall door joined to the hinge, where the rear wall door can pivot on the hinge to extend adjacent an exterior surface of the sidewall structure or can pivot into the volume of the reversibly foldable freight container. In an unfolded state the reversibly foldable freight container has a predefined width measured at a predetermined point on each of two of the rear wall corner posts. A plurality of jointed members in the floor structure allows the reversibly foldable freight container in an unfolded state to move toward a folded state so that the predetermined points on the rear wall corner posts do not extend beyond the predefined width of the reversibly foldable freight container in the unfolded state.
