    Abstract: A pack article includes a flexible container having front, back, right side, and left side panels connected together to define an internal cavity, a flap to enable access to the internal cavity, and at least one divider within the internal cavity connected to and intersecting the back panel at a diagonal, and extending between the right and left side panels to provide a diagonal support surface for an item placed within the pack. The angle of the divider serves to orient the contained load of the pack and direct the weight of the load towards the back panel, thereby distributing the weight along the length of the user's back.
