A multi-material design with a modified polymer topline and expanded lower urethane sole insert lets the Cobra S2 Irons position weight lower and further back, while improving vibration dampening on off-center hits. An improved appearance that will appeal to more players includes the heel and toe inserts hidden away from view, a hidden back flange, shorter blade length, straighter leading edge and a cleaner scoreline pattern. An updated mid-width sole design with trailing edge groove provides the benefits of a wide sole while keeping the leading edge low. Strong lofts and longer lengths combine for increased distance.
