An energy absorber includes a base sheet and a plurality of recovering crush lobes extending from the base sheet. The crush lobes protect an adjacent object by cushioning the blow following repeated impacts in both vehicular and non-vehicular (e.g. helmets) environments. Each crush lobe includes a side wall that is oriented to buckle or bend and then spring back after absorbing energy when impacted. At least one of the base sheet and an end wall of at least one crush lobe optionally includes a number (X) of integrally-formed protruding countermeasures where 0
