Quantum Max Fast is Callaway's lightest fairway wood, built for players who benefit from an overall lighter setup. From head to grip, every component is engineered to make swinging easier, while a high MOI and shallow face profile encourage easy launch, higher flight, and consistent contact. Speed Wave 2.0 Positions up to 40g of weight 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 centerface 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 fairway wood impact patterns. Lightweight, Easy-to-Hit Design Callaway's lightest model for moderate swing speeds. An ultra-forgiving, lightweight design saves weight and increases stability-helping boost clubhead speed, launch higher, and maximize carry with less effort. OptiFit4 Hosel Adjustability (3W-5W) Features independent loft and lie adjustability, offering seven total configurations to fine-tune launch angle and shot shape-whether you're looking for a higher trajectory, straighter ball flight, or a draw-biased setup.
