Features:

• AN INSIDE LOOK
  Every individual iron has a unique internal structure, featuring strategic mass distribution and precision tungsten weighting. This AI-optimized construction is engineered to create an unrivaled blend of distance, forgiveness and accuracy.
• PREMIUM SOUND AND FEEL
  P·790’s forged hollow body is the ideal construction for blending performance with premium feel. An all-new internal sound stabilization bar combines with SpeedFoam Air™ to deliver an elevated forged iron feel.
• INTELLIGENT SWEET SPOT
  The 4140 forged high speed face is 1.56mm at its thinnest location. Combining the responsive face and new internal shaping yields a new sweet spot design, which is a remarkable advancement from the early generations of P·790. This new sweet spot intelligently captures more shots while ensuring consistent ball speeds and accuracy.
• FLTD CG FOR CONSISTENT PERFORMANCE
  FLTD CG™ strategically positions the center of gravity (CG) lowest in the long irons and progressively shifts higher throughout the set. A new thick-thin back wall construction unlocks additional weight redistribution, further optimizing mass properties for pinpoint CG placement. The design produces better launch and playability in long irons with precision control in the scoring clubs.
