Built for the player seeking improved accuracy and maximum distance with a softer feel, DYNAPWR Forged is the result of precise simulations designed to ensure that the sole and face work efficiently in unison. Complete with a stable internal structure and TE-031 Urethane filled cavity, these irons are optimal for players looking for both forgiveness and a traditional clubhead shape. VARIABLE FACE THICKNESS: Optimal clubface thickness is determined by AI simulation, leading to increased flexion and energy transfer for more distance and speed. PKR-CUP FACE: Designed through AI simulation, PKR-Cup Face wraps the perimeter of the sole for maximum flex and consistency. FORGED 8620 CARBON STEEL: One of the softest materials on the market, the Forged 8620 Carbon Steel provides workability and instant feedback at impact. TE-031 URETHANE FILLED CAVITY: A filled clubhead cavity dampens contact vibrations to help improve overall sound and feel. LOW CG, HIGH LAUNCH: Placing the center of gravity lower in the clubhead provides high MOI and a high launch needed to hold greens. POLISHED MIRROR FINISH: Enhances compact look at address, giving the club a players look in a more forgiving package. Grip Model: Lamkin Crossline 360 Black Shaft Manufacturer: KBS Tour Lite Stiff (100g) Shaft Material: Steel Set Composition: 4-PW Warranty: Due to the nature of the game, shaft breaks are replaceable at buyers cost.
