Callaway Women's Quantum Max OS Combo Irons

Callaway's women's Quantum Max OS combo puts the biggest iron head in its 2026 women's line behind a 5-hybrid, and sells the result as one seven-club set: 5-hybrid, 6-iron to PW, gap wedge. The 7-iron is 29 degrees, one softer than the Max Fast version, and the super game improvement footprint is there for one reason, which is that big, forgiving heads make poor contact cost less.

Every club, hybrid included, carries Mitsubishi's Eldio White/Silver 40 in ladies flex, with a Lamkin ST Soft grip. Both hands are offered, which matters, because the women's Max Fast combo is right-handed only. Between the two, the OS combo is the choice when contact is the problem; the Max Fast combo when weight is. The extra head size is easy to see at address, and for the golfer it's meant for, that's the reassurance it's meant to give.
