This variation of the Srixon ZX5 MK II irons includes 5 to Pitching Wedge and an Additional Wedge, all with graphite shafts. Made for golfers who prefer graphite shafts for their lighter weight and vibration dampening, these clubs promote smoother swings and enhanced feel. Similar to the 4-PW set, these irons are crafted in China and covered by a limited 1-year warranty against manufacturing defects on club heads.
