Ladies Callaway Quantum Max OS Golf Irons

The Callaway Quantum Max OS women’s irons are built for golfers who want help launching the ball and more forgiveness across the face. Callaway classifies this oversized design as super game improvement: the larger profile provides a reassuring view at address, while the high-launching design is intended to support speed, carry and consistency on imperfect strikes. This makes the set a considered option for players developing confidence or seeking more help on approach shots.

Stock women’s builds use a lightweight Mitsubishi Eldio White/Silver 40 graphite shaft in ladies flex and a Lamkin Comfort ST+2 women’s grip. The available 4-iron through sand wedge progression gives golfers a broad set of gapping choices, though the exact clubs supplied depend on the retailer’s set configuration. Right- and left-handed options and selected custom high-launch specifications may be available.

The published women’s loft progression runs from 19° in the 4-iron to 55° in the sand wedge. For a reference point, the 7-iron is 29° loft, 62.25° lie, 36.25 inches long and has 4.80 mm offset. Check the retailer’s set composition, hand and shaft before purchase; a fitting can help match the gapping and lie to your swing.

The Bold Golfer FAQs

Got questions? We’ve got answers! If you do not find your answer here, please use the contact page to let us know.

What makes The Bold Golfer different from a traditional online pro shop?

Unlike standard retail outlets, we do not stock physical inventory, manage transactions, or ship orders. We operate as an independent golf publication and globally aggregated product catalog, sourcing real-time deals from trusted manufacturers and merchants worldwide to simplify your golfing gear research.

How do your country-specific live pricing buttons work?

We partner with premium golf merchants across different continents. When browsing a product, simply click the button matching your region (e.g., USA, UK, AUS, or EU) to be directed instantly to an authorised local retailer with current stock and localised pricing.

Do I pay any extra fees or hidden premiums by using your outbound links?

No. Every outbound link on our site redirects you directly to the official merchant's checkout at zero extra cost to you. Our platform is fully supported through tracking commissions paid to us by our retail partners when you complete a qualifying purchase.

Who should I contact if I have an issue with an order or a delivery delay?

Because all sales are finalised directly on our partner merchants' secure websites, any questions regarding order processing, shipping, tracking numbers, or returns should be handled directly with the specific retailer you purchased from.

Are the products featured on your site brand new or pre-owned?

Our automated product feeds primarily highlight brand-new, current-generation golf equipment from major manufacturers. However, when we link to specialised premium clearance warehouses, any pre-owned or refurbished status will be clearly indicated on the partner site.

How do you choose which golf brands and products to feature on your website?

We select brands based entirely on manufacturing compliance, tournament-tested reputation, and user feedback. From industry titans like TaylorMade and Callaway to elite direct-to-consumer simulator labels, we aim to cover the full spectrum of high-performance gear.

How often is the product data and retail stock updated?

We utilise dynamic product data feeds that sync regularly with our global affiliate networks to ensure that our configurations, manufacturer names, and global retail channels remain accurate for our community of golfers.
