Abstract: A backpack frame is disclosed herein. The backpack frame includes a frame body and an arm coupled to the frame body. The arm has a proximal portion at the one or more points of connection and a distal portion that is extended away from the one or more points of connection. A space between a distal portion of the arm and the frame body is sufficiently sized to receive the head of an antlered animal therethrough when the distal portion of the arm is pivoted away from the frame body. The arm is capable of pivoting at a point of connection between the arm and the frame body. Accordingly, at least in some instances, when the head of an antlered animal is inserted through the space, the arm pivots, locking the head in place and supporting the head and antlers.
