The SPEEDZONE irons feature a breakthrough in performance with our first ever Carbon Fiber Topline, delivering an ultra low CG for maximum speed and launch.
CARBON FIBER TOPLINE
Carbon fiber has a higher strength to weight ration than steel, and saves 3 grams to lower the CG and maximize ball speed.
FORGED PWRSHELL FACE
A forged PWRSHELL face insert features a 35% larger Sweet Zone area, and a 8% deeper undercut to enhance ball speed and launch across the face.
SPEEDBACK SHAPE
Extreme heel and toe weighting creates a lower CG and a higher MOI than most traditional iron shapes allow.
CO-MOLD MEDALLION
A lightweight medallion features aluminum, TPU, and acrylic foam that work together to damp vibrations for excellent sound and feel.
