An inversion-formed double-walled tube (20) includes an outer tube (40) having an outer wall thickness (to), an inner tube (30) disposed inside the outer tube (40) and having an inner wall thickness (ti), and a transition portion (50) connecting the inner tube (30) and the outer tube (40). In this arrangement, at least one of the inner (ti) and outer wall thicknesses (to) varies along a length of the double-walled tube (20). The inversion-formed double-walled tube (20) may be configured as an inversion tube type energy absorber and as an energy absorbing inversion tube assembly.
