Callaway Quantum Max OS Combo Irons

The oversize Quantum Max OS is already the most forgiving iron in Callaway's 2026 range, and the combo set pushes the idea one club further by replacing the 5-iron with a 5-hybrid. The stock build is a 5-hybrid, then 6-iron to pitching wedge, then an AW, seven clubs, with the cast 17-4 stainless irons carrying a 29 degree 7-iron and a super game improvement footprint.

Shafts match the standard OS set: True Temper's Elevate 85 in steel, Project X's Denali Frost Silver and Mitsubishi's Vanquish PL in graphite, senior through stiff, with the hybrid on a 60 gram Denali Frost Silver. Both hands are covered. Buy it if you already know the 5-iron never gets hit well, and the 6-iron is close to the limit too; the hybrid at the top takes the hardest club out of the bag before it ever gets there.
