A load support system is provided including a flexible frame unit attached to a shoulder support structure and to a hip belt assembly. The frame is pivotally attached to the hip belt assembly and is held in a slightly bowed configuration, whereby load is transferred from the frame to the hip belt through pivot points and a venting space is created between the frame and a user's back. The shoulder support structure preferably includes a pair of independently positionable shoulder straps that are removably attached to the frame. The hip belt assembly preferably includes a load support belt that may be coupled to the frame, and a hip pad coupled to the load support belt via a hook and loop fastening system. The suspension system may be used to support backpacks, and the like, or may be adapted for other applications including SCUBA tank support. The suspension system may be adjusted independently of the load and affords considerable freedom of movement when worn, due particularly to the pivotal attachment of the hip belt assembly to the frame and to the form of the flexible frame.
