JJ Spaun just kept grinding. Honestly, if you watched the 2025 U.S. Open at Oakmont, you saw a guy who looked like he was about to fall apart on the front nine, only to turn into a total assassin with the flatstick. That 64-foot birdie bomb on the 72nd hole? Pure theater. But while everyone is talking about the trophy, gear nerds (like us) are staring at the dirt on his soles and the shafts in his woods.
See, Spaun is technically a Srixon staffer, but his setup is a fascinating "Frankenstein" bag. He doesn’t just play what he's told; he plays what actually works under the most brutal pressure in golf. From a Titleist driver to a putter that looks like a brand-new Star Wars prop, the JJ Spaun what's in the bag story is a masterclass in why you shouldn't feel forced to play 14 clubs from the same brand.
The Big Stick: Titleist GT3 Driver
It’s kinda funny when a Srixon-sponsored pro pulls the headcover off a Titleist, but here we are. Spaun has been leaning heavily on the Titleist GT3.
He keeps it at 9 degrees of loft.
The shaft is the real story, though. He’s got a Fujikura Ventus Black 6 X (the newer VeloCore+ version). It’s a stout, low-launch, low-spin monster. For a guy who isn't the biggest hitter on tour, that stability is what kept him in the narrow fairways at Oakmont. He ranks surprisingly high in total driving, and this combo is the reason why.
Fairway Woods: A TaylorMade Tandem
When he moves to the "long grass" clubs, he switches brands again. He's currently gaming the TaylorMade Qi10 series.
- 3-Wood: 15 degrees with a Mitsubishi Diamana PD 70 TX shaft.
- 5-Wood/7-Wood: He alternates depending on the course, but at the Open, he leaned on an 18-degree Qi10 5-wood.
Interestingly, he uses the Mitsubishi Diamana PD 80 TX in his higher-lofted wood. It’s a very heavy, stable profile. While many pros are moving toward lighter, faster shafts, Spaun goes for the "heavy lumber" feel to ensure he doesn't lose it left when the adrenaline kicks in.
The Scoring Tools: Srixon & Cleveland
This is where his sponsorship deal actually shows up. Spaun’s iron play is the most underrated part of his game. He uses a "combo set" because, let's face it, nobody wants to hit a bladed 4-iron into a 240-yard par 3.
Iron Breakdown
He starts with a Srixon ZXi5 4-iron. It's got that extra bit of "oomph" and forgiveness. From the 5-iron down to the pitching wedge, he’s in the Srixon ZXi7. These were actually rated as some of the best players' irons of 2025 by independent testers, and JJ proved it. He hits them with True Temper Dynamic Gold Tour Issue X100 shafts. No graphite here—just old-school, heavy steel.
The Wedges
He doesn't use Vokeys. He stays in the family with Cleveland.
- 50°: Cleveland RTX ZipCore (Mid Bounce)
- 54°: Cleveland RTZ (Full Sole)
- 60°: Cleveland RTX 6 ZipCore (Low Bounce)
He's got the Dynamic Gold S400 shafts in these. That’s a standard tour pro move—slightly softer than his iron shafts to help with "feel" on those touchy chips around the green.
The Putter That Changed Everything: L.A.B. Golf DF3
If you haven't heard of L.A.B. Golf yet, you've been living under a rock. Or a bunker. Spaun’s win was basically a 4-day commercial for their DF3 model. It’s a Lie Angle Balanced putter, which basically means the face stays square to the arc without you having to do anything.
The specs are specific:
- Length: 34 inches
- Lie Angle: 70 degrees
- Shaft: L.A.B. Golf x TPT (Carbon fiber)
- Grip: An old-school Scotty Cameron Black Studio Design.
Wait, what? Yeah, he put a Scotty grip on a L.A.B. putter. It’s a weird mix, but considering he made 136 feet of putts in his final seven holes at the U.S. Open, nobody is going to tell him to change it.
The Small Details
He plays the Srixon Z-Star Diamond ball. It's the "tweener" ball in Srixon's lineup—more spin than the Z-Star XV but more distance than the standard Z-Star. It’s perfect for a guy who needs to hold firm greens but still wants to be able to compress the ball off the tee.
His grips? Golf Pride Tour Velvet. Simple. Classic.
What Can You Learn From JJ Spaun's Bag?
Honestly, the biggest takeaway here is the "mixed bag" philosophy. Spaun is a Major winner now, and he did it by ignoring brand loyalty where it mattered. He chose the Titleist driver because it performed better. He chose the L.A.B. putter because it made more putts.
If you're looking to upgrade your own gear based on the JJ Spaun what's in the bag list, don't just buy the whole set. Start with the putter—the DF3 is genuinely transformative for people who struggle with a rotating face. If you're a faster swinger looking for a driver that won't balloon on you, that Ventus Black/GT3 combo is as legit as it gets.
Don't be afraid to mix and match. Your score doesn't care if your bag looks like a catalog, it only cares if the ball goes in the hole. Go get a fitting, try some "weird" putters, and stop worrying about having matching headcovers. It worked for JJ, and it'll probably work for you too.
