Callaway Quantum Max OS Hybrid

OS means oversize, and at 130cc this is the biggest hybrid head Callaway lists for 2026. Six lofts cover 18 through 32 degrees, cast with a 455 Carpenter steel face, and unusually for a game-improvement shape the sole weight moves as well as the hosel turning.

Shafts run three deep, Project X's Denali Silver in 60 and 70 with a Vanquish 50 underneath, in senior, regular or stiff. Nothing firmer is listed. That ceiling is consistent with the head, which is drawn to be forgiving rather than workable, and a large footprint paired with genuine adjustability is rarer in this category than it ought to be. Both hands are built, across all six lofts.
