The Cobra 3100 I/H advanced undercut design pushes weight low and back for a deep centre of gravity and high moment of inertia. This results in higher shots that fly further. The 'Undercut' design of the 3100 irons give the maximum amount of forgiveness and a low centre of gravity. This helps to make your long irons some of the easiest to use on the market! The Urethane insert dampens vibration for superior feel. Made from high quality 431 Stainless Steel this club is perfect for the golfer who wants the perfect balance of accuracy, forgiveness and distance. A 'Super-sized' sweet zone across the whole club face provides exceptional forgiveness on off centre strikes. Fitted with Cobra Golf Pride Tour Velvet grips and high quality Nippon steel or Aldila graphite shafts as standard to give greater club head speed for extra carry and distance.
