An inversion-formed double-walled tube includes an outer tube having an outer wall thickness, an inner tube disposed inside the outer tube and having an inner wall thickness, and a transition portion connecting the inner tube and the outer tube. In this arrangement, at least one of the inner and outer wall thicknesses varies along a length of the double-walled tube. The inversion-formed double-walled tube may be configured as an inversion tube type energy absorber and as an energy absorbing inversion tube assembly.
