“The low-spin fairway partner in the ST-G family - Mizuno's titanium fairway push for better players. Rung-3.”

The ST-G Titanium fairway wood, released October 2023 with the ST-G driver, is a rare thing: a full-titanium fairway built to be the flattest, lowest-spinning on the market for better players. Rather than the usual steel or steel-composite build, Mizuno used a lightweight 811 Ti body and Ti face, then re-invested the saved grams into an 80-88g high-density steel sole weight to drive the CG deep and low. An internal 'waffle' crown pattern shaves further mass, and a composite wrap over the toe pulls weight out of the upper head. The result is a deep-faced 3-wood (15 degrees) and 5-wood (18 degrees) with a penetrating, boring flight off tee and turf — plus the CORTECH Chamber and a Quick Switch hosel for 4 degrees of adjustment. Reviewers praised its looks, sound and feel.

Notable for its uncommon all-titanium construction in a fairway wood and its niche as a low-spin better-player option, drawing dedicated writeups from Golf Monthly and Golf.com — but it is a small-volume specialty club with no cult following or collector premium. Its distinction is engineering (titanium body, deep steel sole weight), not market standing.

For low-handicap, faster swingers (~80-105 mph) who fight high spin and a ballooning fairway-wood flight and want a flatter, more penetrating trajectory off the tee and from tight lies. The 15-degree 3-wood is the natural pick for a strong-lofted long option. Higher-handicap or slower-speed players who need help getting a fairway wood airborne should choose a shallower steel or steel-composite model (e.g., an ST-Z 230 fairway).

• Full-titanium construction: 811 Ti body and Ti face — unusual for a fairway wood — freeing mass for an ~80-88g high-density steel sole weight to lower and deepen the CG.
• Internal 'waffle' crown pattern plus a composite wrap over the toe section remove weight high in the head for the penetrating, low-spin flight.
• Offered as a 15-degree 3-wood and 18-degree 5-wood with a Quick Switch hosel giving 4 degrees of loft adjustment (reviewers note the face opens noticeably when lofted down).
• Uses the same CORTECH Chamber energy-return concept as the ST-G/ST-230 drivers, adapted to the fairway head.
• MSRP $399.99 at launch.

Launched into a fairway-wood market that had largely standardized on steel or steel-carbon construction (TaylorMade Stealth 2, Titleist TSR2/TSR3, Ping G430, Callaway Paradym), making its full-titanium build a genuine outlier — closest in spirit to TaylorMade's occasional titanium/low-spin fairway experiments. It sat as the players' fairway opposite Mizuno's more forgiving ST-Z 230 and ST-Max 230 fairway woods.

Launched at $399.99. In 2026 it is a niche used item: reconditioned-retail runs roughly $180-260, while realistic private-party prices are about $130-220 on eBay/SidelineSwap depending on loft, shaft and condition. Titanium fairways draw slightly more enthusiast interest than ordinary steel ones, but volume is thin and it does not appreciate.
