One embodiment of the present invention relates to a user based carrying system capable of independent transportation of a load including a hip-based user attachment system. The carrying system includes an enclosure member having an internal region encased by an internal surface. A user attachment system releasably secures the carrying system to the user for independent transportation without requiring muscular engagement. The user attachment system includes a hip attachment system with a dorsal articulation member and a strap member. The dorsal articulation member includes a front and rear member three-dimensionally moveably coupled to one another. The rear member is coupled to the enclosure member and the front member is coupled to the strap member. The three-dimensional moveable coupling between the front and rear members includes three restricted degrees of freedom configured to efficiently absorb corresponding user hip movements and directly support other user hip movements.
