Enhanced performance and visual appeal combine to form PING G410 Irons. Cor-EYE Technology combines with top rail undercut and cascading sole design features to create a more flexible, free-moving face and produce the highest face deflection PING has ever used in an iron. Toe and hosel weighting reallocate weight to the extremes for increased MOI and stability. The co-molded cavity badge utilizes aluminum and santoprene elastomer to damp vibrations and create powerful sound.
