The Big Bertha Irons can make you up to 2 clubs longer. For the first time were putting the Cup 360 Face Technology we use in fairway woods into our irons. Up to 2 Club Longer DistanceUp to 2 clubs longer is for real. HIGHER BALL SPEED all across the face comes from the same 360 Face Cup technology we put in fairway woods. Combined with an Internal Standing Wave this is the hottest iron weve ever produced.Maximum ForgivenessYour shots will launch higher and fly straighter. Hollow body construction lets us put the weight where we want it so you get an incredibly forgiving iron.More Flexible FaceA more flexible iron face helps the ball jump off the club with serious ball speed behind it. It adds to the forgiveness too the ball speed is high wherever you hit it on the face.Advanced Progressive LooksThe sole designs are what you want to see wider in the longer irons to give you confidence narrower in the shorter irons because we know youll hit those well. With a progressive modern topline you can take one look at the Big Berthas and know that theyll work for you.Premium Shaft OptionsWere combining our best Big Bertha technology with some of the most premium aftermarket shafts out there. Choose from the UST Recoil shaft in graphite or the True Temper SpeedStep 80 in steel.
