Abstract: A backpack system or personal load bearing system uses a lightweight, SRC (semi-rigid core) and hanger suspension system, that compresses the center of the body between the xiphoid process and the lower back to a compressive force to transfer the load upward and forward while freeing up the shoulders. The SRC is provided that is made out of a semi-rigid plastic such as ABS plastic, carbon fiber composite or any other non-compressible material with similar structural characteristics. Left and right hooks pass over, forward and downward over the chest and are joined at a central coupling at a center of the human body, the “xiphoid process”, a small extension of the sternum. Right and left lower straps extend to left and right lower support sites to form a arched cage on the user. A belt wraps around the waist on top of the hip bones to limit lateral movement.

Abstract: A heavy-duty, modular backpack system or personal load bearing system replaces shoulder straps with a lightweight, SRC (semi-rigid core) and hanger suspension system, that subjects the chest or center of the body to a compressive force to transfer the load forward while freeing up the shoulders. The SRC is provided that is made out of a semi-rigid plastic such as ABS plastic or a carbon fiber composite or any other non-compressible material with similar structural characteristics.
