Modern 360 ° Undercut CavityAt the core of the Quantum Max Fast is Callaway’s Modern 360 ° Undercut Cavity. This advanced two-piece construction uses extreme perimeter weighting and a fully exposed undercut to increase face flex where golfers need it most. The result is faster ball speeds, higher launch, and improved forgiveness across the face, particularly on strikes that miss the centre.Next Generation Ai-Optimised Face DesignThe Next Generation Ai-Optimised Face intelligently shapes the face geometry based on real-world impact patterns. By expanding the effective sweet spot, it delivers more consistent ball speed, launch, and spin, helping shots fly higher and carry more reliably even when contact varies.Progressive Tri-Sole DesignThe Progressive Tri-Sole Design adapts sole geometry throughout the set to promote cleaner turf interaction and efficient speed retention. Wider soles in the long irons help launch the ball higher and maintain carry, while more refined soles in the short irons and wedges improve control and consistency through impact, even on heavier strikes.Urethane MicrospheresUrethane Microspheres are integrated into the head to absorb unwanted vibration at impact. This enhances sound and feel, delivering a softer, more forged-like sensation despite the high-speed, game-improvement construction of the iron.Oversized, Confidence-Inspiring ShapeQuantum Max Fast pairs its lightweight design with an oversized profile that inspires confidence at address. The shape helps golfers set up comfortably and commit to the swing, supporting higher launch and more consistent contact throughout the set.On-Course PerformanceOn the course, the Quantum Max Fast irons produce a high, easy launch with stable flight and dependable carry distances. Long irons get airborne with noticeably less effort, while mid and short irons offer predictable distance control into the greens. Off-centre strikes retain ball speed and direction effectively, helping maintain confidence and scoring opportunities even when swing consistency varies.Who It SuitsThe Quantum Max Fast irons are ideal for golfers with moderate swing speeds who want help generating height, speed, and distance. They suit players looking for maximum forgiveness and easy launch in a lightweight iron, without moving into a harsh-feeling or overly bulky design.Specifications Club Loft Lie Length Offset Dexterity 5 22 ° 60.75 ° 38.75” 5.72mm RH 6 25 ° 61.375 ° 38.125” 5.18mm RH 7 28 ° 62.0 ° 37.5” 4.67mm RH 8 32 ° 62.5 ° 36.875” 4.41mm RH 9 37 ° 63.0 ° 36.25” 3.61mm RH PW 42 ° 63.25 ° 36.0” 3.07mm RH AW 46 ° 63.5 ° 35.75” 2.06mm RH GW 50 ° 63.75 ° 35.5” 2.06mm RH SW 56 ° 64.0 ° 35.25” 2.06mm RH
