Justin Thomas WITB

Justin Thomas is a two-time major champion and one of the best iron players in golf, and he games a full Titleist setup that mixes brand-new prototype gear with a genuinely old fairway wood he still trusts. His 2026 what-is-in-the-bag is built around personalized irons and precise wedge gapping. Below is his verified bag, club by club, followed by the story behind the key gear.

The story behind Justin Thomas' bag

Thomas' bag blends the cutting edge with the well-worn. He plays prototype irons built to his spec and a putter he changed for 2026, yet he still carries a Titleist 915Fd 5-wood that is roughly a decade old. It is a reminder that a great player keeps the clubs that work no matter their age, and only changes the ones he can genuinely improve. Everywhere else the bag is classic Titleist, tuned to his exacting standards.

Driver and fairway woods

Thomas games a Titleist GTS2 driver at 9.5 degrees with a Mitsubishi Diamana Whiteboard 63 X shaft, a classic-profile shaft he has favored for years. His fairway woods tell the real story: a Titleist TS3 3-wood and, remarkably, a Titleist 915Fd 5-wood that is around a decade old and that he has kept through countless newer releases. Trusting an old fairway wood that still performs is one of the most instructive choices in his bag.

Irons

Thomas plays a combo iron set: a Titleist T250 in the 4-iron for distance and forgiveness, a T100 in the 5-iron, then Titleist 621.JT Prototype blades from the 6-iron through 9-iron, all on heavy True Temper Dynamic Gold Tour Issue X100 shafts. The 621.JT protos are built specifically for him, and blending a distance long iron into personalized blades is a classic setup for one of the game's elite ball strikers.

Wedges

Around the greens Thomas carries four Titleist Vokey wedges with finely tuned lofts: an SM11 46 bent to 47.5, a 52 bent to 52.5 and a 56 bent to 57, plus a Vokey WedgeWorks Proto 60 bent to 60.5. Bending each wedge a fraction to achieve perfectly even gapping is a hallmark of a meticulous player, and it removes the awkward in-between distances that cost amateurs strokes.

Putter

On the greens Thomas switched to a Scotty Cameron Phantom 9.5 mallet in 2026, moving from a blade to a higher-MOI mallet for more stability and a more forgiving roll. It is a notable change for a player who had long used a blade, and it fits a wider tour trend of top players trusting mallets for consistency under pressure.

Golf ball

Thomas plays the Titleist Pro V1x, the firmer, higher-flying, higher-spinning of Titleist's two tour balls. It is the same ball amateurs can buy; see our Titleist Pro V1x review for how it performs for the rest of us.

What you can learn from Thomas' setup

The big lesson from Thomas is that age does not matter if a club works: he keeps a decade-old 5-wood simply because he trusts it, and that kind of confidence is worth strokes. His even wedge gapping is well worth copying, as tightly spaced lofts remove awkward part-shots, and his move to a mallet putter mirrors a smart trend toward forgiveness on the greens. His prototype blades are elite, but the combo iron idea of an easier long iron blending into players' irons is sound for most golfers.
