Ever wonder how Justin Thomas hits those piercing iron shots or bombs his driver down the fairway with such control? A huge part of his success comes down to the carefully selected tools in his Titleist staff bag. This is a complete guide to Justin Thomas’s go-to golf clubs, breaking down his entire setup from the driver that launches his tee shots to the putter he trusts to sink crucial putts. We’ll also add some coaching takeaways to help you understand how his choices might inform your own equipment decisions.
Justin Thomas is a Titleist staff player through and through, and his bag reflects a deep trust in their equipment. What’s fascinating about his setup, often referred to as his WITB (What’s In The Bag), is that it’s not just a collection of the newest models. It’s a purposeful blend of modern technology, like his driver, and classic, forged-blade irons that reflect his incredible ball-striking skill. His bag is a masterclass in building a set that complements your strengths, a lesson every golfer can learn from.
At the top of his bag, JT plays a Titleist TSR3 driver. He typically sets the loft at 10 degrees but may adjust it slightly depending on course conditions. The TSR series is known for its speed and stability, but the reason a player like Justin Thomas chooses the TSR3 model specifically is its fine-tuned adjustability. The TSR3 features a SureFit CG track with a movable weight, which allows elite players to dial in their preferred shot shape and launch conditions with extreme precision. For JT, this means a C2 setting that helps negate a miss to the left and promotes the slight fade he often likes to play off the tee, giving him confidence to swing away.
You don’t have to be a top pro to benefit from an adjustable driver. Most modern drivers have adjustable hosels and movable weights for a reason. Instead of just setting it to "standard" and forgetting about it, learn what the settings do. If your consistent miss is a slice (left to right for a righty), moving the weight towards the heel can help the face close more easily through impact. If you hit the ball too high with too much spin, lowering the loft can help. Experimenting on the range can help you find a setting that doesn't fix your swing, but rather complements your natural tendencies and makes your good shots even better.
For his 3-wood, JT also trusts the Titleist TSR3, perfectly gapping from his driver. This club is a true workhorse, serving two critical functions: as a fairway-finder off the tee on tight par 4s and a potent weapon for attacking long par 5s in two. He opts for a shaft that is slightly heavier than his driver shaft, a common practice among pros seeking more control and a lower, more piercing flight from their fairway woods. The reliable performance and look of the TSR3 give him the confidence to hit a variety of shots, from a high-sailing approach to a low, running tee shot.
Ask yourself: what's your most reliable club off the tee when your driver isn't cooperating? For many amateurs, a 3-wood can be tough to hit consistently, especially off the deck. It might be time to consider a 5-wood or even a 7-wood. These clubs have more loft, making them easier to launch and often more forgiving. Check the distance gaps in your own bag. Having a trustworthy fairway wood is essential for good course management and avoiding big numbers.
Here’s where JT truly separates himself as one of the game's elite ball-strikers. His iron setup is a brilliant example of a "combo set," where forgiveness and playability are strategically blended. For his 4-iron, he carries a Titleist T200. This is a player's distance iron that provides a bit more forgiveness, a higher launch, and more speed at the top end of the set - perfect for long approaches into greens.
From the 5-iron down to the 9-iron is where the artist comes out. JT plays with a stunning set of custom Titleist blades, stamped "621.JT." These are prototype muscle-back (MB) irons forged specifically for him. Muscle-back blades have a very small sweet spot and offer virtually no forgiveness on off-center hits. However, for a player who can consistently find the middle of the face, they provide unparalleled feedback, feel, and the ability to shape the ball on command (a draw or a fade), which is why pure strikers like JT prefer them.
Blade irons are beautiful, but they are designed for the best strikers on the planet. For the vast majority of amateur golfers, playing a full set of blades will do more harm than good. Be honest about your own game. A cavity-back iron (like a Titleist T200 or T350) is designed with perimeter weighting to make the club much more stable and forgiving on mishits. This means your off-center shots will still fly straighter and closer to your intended distance. The most important lesson from JT’s irons is that you must match your equipment to your ability level. Choosing a more forgiving iron is one of the smartest decisions an amateur can make.
Around the greens, Justin Thomas becomes a magician, and his Vokey wedges are his wands. He carries four of them, allowing him to cover precise distances inside 130 yards and hit any type of creative shot the situation demands. Wedge guru Bob Vokey works personally with pros like JT to craft the perfect combination of loft, bounce, and grind for their game.
JT's setup features remarkably specific lofts (like a 60.5° lob wedge) to hit exact yardages. The "grind" refers to the shaping of the sole of the wedge, which affects how it interacts with the turf. A player with his level of skill uses different grinds to open the face for a flop shot, play a low-checking pitch shot, or blast out of a soft bunker.
The scoring zone is where amateurs can make the biggest gains, and wedges are a huge part of that. Two things to focus on: gapping and bounce. Make sure you don't have a massive yardage gap (more than 15 yards) between any of your wedges. Second, understand bounce. Bounce is the angle on the sole that prevents the wedge from digging into the ground. If you play on soft courses or have a steep swing, you likely need more bounce. If you play on firm, tight lies, less bounce and a more versatile grind could be better. Getting fitted for wedges is one of the quickest ways to improve your short game.
For years, Thomas was known for his love of a classic Scotty Cameron Newport blade-style putter. However, in recent years, he has made a notable switch to a mallet-style putter - the Scotty Cameron Phantom X 5.5. This kind of switch is often made for one key reason: stability. Mallet putters generally have a higher Moment of Inertia (MOI), which means they are more resistant to twisting on off-center strikes. Put simply, they are more forgiving.
The "5.5" model is particularly interesting because it incorporates a small slant neck ("jet neck"), which gives the putter some "toe hang." This is a feature often found in blade putters that suits a player with a slight arc in their putting stroke. This allows JT to get the forgiveness benefits of a mallet while retaining a feel that is similar to what he grew up using.
Don't just grab a putter off the rack because a pro uses it. The most important thing is finding a putter that matches your putting stroke. Go to a golf shop and ask an expert to watch you make a few strokes. If you have a "straight back, straight through" motion, a "face-balanced" putter (typically a mallet with a double-bend shaft) will work best for you. If you have a noticeable arc, a putter with some degree of "toe hang" will suit you better. Finding the right style will help you deliver a square face to the ball more consistently.
Justin Thomas's bag is a perfect reflection of his game: powerful, precise, and highly customized. By blending forgiving technology where he needs it (in the long irons) with player-focused feel and workability in his scoring clubs, he has built a set that allows him to compete at the highest level. His choices offer valuable insight for all golfers looking to optimize their own equipment.

Before the days of giant, 460cc titanium drivers that sound like a firecracker, the king of the golf bag was a beautiful, hand-crafted club made from persimmon wood. If you've ever heard old-timers talk about the feel of a purely struck shot, they were likely reminiscing about these classic clubs. This article will walk you through what Persimmon clubs are, their place in golf history, how they perform against modern equipment, and some practical advice if you decide to tee one up.
