Cobra Golf S9 II Individual Iron with Graphite Shaft Cobra engineers made their award-winning S9 irons even better. The expanded 3-piece polymer topline and urethane sole insert on the S9 II Irons optimize discretionary weighting for a lower CG and higher moment of inertia. This means higher launch, greater distance and more accuracy for players. Combine that with the club's low profile and wide sole with a chamfer relief design and you gain improved versatility and more forgiveness on the links. Features: Wide sole Low profile head design Three-piece polymer topline Urethane insert Back cavity plate
