An energy absorber 16 comprising a carrier 18 having a wall 22 extending along a longitudinal axis, the wall having first and second legs 24, 26 spaced apart from each other and extending in a first direction away from the wall. A plurality of fins 28 extend from the wall in the first direction, at approximately 60-65 degrees relative to the wall. The fins may be fixed to the wall or the legs, and could taper away from the legs. The wall, legs and fins may be integral with each other, or alternatively just the wall and fins may be integral. Preferably, the absorber further comprises a second plurality of fins extending from the wall in the first direction, at approximately 60-65 degrees in a negative direction relative to the wall. The energy absorber may be mounted to a bumper beam 14, wherein either the legs and fins abut the bumper beam, or just the fins abut the bumper beam.
