The present invention relates to a backpack system for transporting items and an accompanying device. In exemplary embodiments, carried items are kept secure within a plurality of item holders to prevent the items from moving. The item holders can be rigid structures like cylinders or flexible canvas pouches. In exemplary embodiments, the backpack system can have configurations for carrying either a device or additional items.

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.
