Abstract: A novel backpack frame and backpack are described where the frame has a common point from which a pair of upper vertical support members ascend and a pair of lower vertical support members descend. The lower vertical support members are mirror images of each other and one lower vertical support member has a twist in a first direction to form a latitudinal concavity relative to the back side of the backpack and another lower vertical support member has another twist in a second direction to form another longitudinal concavity relative to the backpack back side, where the second direction is opposite to the first direction.
