Quantum Max OS features an oversized, draw-biased shape with high MOI, designed for easy launch and maximum forgiveness. Ideal for golfers who struggle with a right miss or need help with getting the ball airborne.
Speed Wave 2.0
Positions tungsten low and forward for faster ball speeds and consistent launch. The new Speed Wave 2.0 design frees up even more face flex, boosting energy transfer—especially on low-face strikes.
New Step Sole Design
The new Step Sole Design reduces turf contact on the sole for efficient strikes and consistent center-face contact. A reshaped heel adds stability through impact, helping keep the face square for greater control and accuracy.
Next Generation Ai-Optimized Face Design
Consistent performance across the entire face, thanks to smarter face flex unlocked by Ai. Every part of the face is precisely tuned through advanced Ai modeling to optimize speed, spin, launch, and accuracy based on real hybrid impact patterns.
Fine-Tuned Flight and Forgiveness
Heel-toe weighting supports straighter shots or subtle shot shape correction, while the OptiFit4 hosel lets you adjust loft and lie for optimized launch, gap consistency, and seven unique ball flight options.
Oversized, Forgiving Shape
Quantum Max OS exhibits a friendly, forgiving look at address in an oversized shape and transitions perfectly with the Quantum Max OS Irons.
