Jackson Koivun’s Complete WITB
Koivun is a Titleist staffer through nearly his entire bag — driver, woods, irons, wedges, and ball. Only his putter, a Scotty Cameron tour prototype, sits outside the brand.
Driver: Titleist GT2, 8° — Fujikura Speeder 661 TR X
3-Wood: Titleist GTS3 Prototype, 15° — Graphite Design Tour AD DI 80g X
Irons: Titleist T250 (3-iron), Titleist T100 (4-iron), Titleist 620 MB Prototype (5–9) — Graphite Design Tour AD DI HY 95X (3-iron), Project X 6.5 (4–PW)
Wedges: Titleist Vokey Design SM11, 46°/50°/54°/60° — Project X 6.5 (46°, 50°), Project X 6.0 (54°), Project X iO 6.0 (60°)
Putter: Scotty Cameron Phantom 9.5R Tour Prototype — SuperStroke Zenergy Pistol GT grip
Golf Ball: Titleist Pro V1
This complete setup was documented during Koivun’s 2026 3M Open victory. A later September 18, 2026 report documented a TaylorMade Qi4D 16.5-degree fairway wood, but did not provide a complete replacement bag.
Why the Titleist GT2 Fits His Game
The GT2 leans toward forgiveness over raw speed — a deliberate choice for a player who prioritizes fairways over maximum distance. At 8 degrees of loft with a Fujikura Speeder 661 TR X shaft, it’s built for a controlled, penetrating flight rather than a high-launch bomber’s setup.
Should You Play a Forgiveness-First Driver Like This?
Maybe — it depends on whether your miss costs you more in accuracy or in distance. The right driver profile matches your own speed, launch, and typical miss, not a tour player’s choice.
Two Documented 2026 Fairway-Wood Snapshots
Koivun’s 3M Open-winning setup was documented with a 15-degree Titleist GTS3 Prototype. At the Biltmore Championship, GOLF reported on September 18, 2026, that he added a TaylorMade Qi4D 16.5-degree fairway wood. The report did not disclose the shaft or establish whether the Qi4D permanently replaced the GTS3, so both remain dated tournament observations.
Why He Blends T250, T100, and 620 MB
Koivun doesn’t play one matched iron set — he blends three different Titleist models across the bag, a common pattern among elite ball-strikers who want a different job from each part of the set.
Should Your Irons Be Blended?
Often, yes — many golfers benefit from more forgiveness in the long irons and more control in the scoring clubs, rather than one iron head trying to do both jobs.
Why Four Wedges
Koivun carries four Vokey SM11 wedges — 46°, 50°, 54°, and 60° — with the shaft weight actually getting lighter as the lofts get higher (Project X 6.5 in the gap wedges, dropping to 6.0 and then iO 6.0 in the lob wedge). That’s a deliberate progression: slightly softer, more feel-oriented shafts in the clubs used for the most delicate, touch-dependent shots around the green.
Loft progression: 46° → 50° → 54° → 60°, keeping consistent 4-to-6-degree gaps through the entire scoring range rather than leaving a big jump anywhere in the set.
Why the Phantom 9.5R
The Scotty Cameron Phantom 9.5R Tour Prototype is a mid-mallet shape — more stability than a classic blade, without going as far toward face-balanced as a full mallet. Paired with a SuperStroke Zenergy Pistol GT grip, it’s a setup built for a stable, repeatable stroke rather than one that favors a lot of arc or manipulation.
Why the Pro V1
Koivun plays the standard Titleist Pro V1 rather than the firmer, higher-spinning Pro V1x — a choice usually associated with players who want a slightly softer feel and more workability off the tee and through the irons, at the cost of a touch less distance than the V1x offers some players.
Koivun Plays a Pro V1. Should You?
The right ball for you depends on your own swing speed, launch, spin, feel preference, and short-game needs — not simply which ball a tour winner happens to play.
How His Bag Compares to Other Tour Players
Koivun’s setup reads as a “control over raw power” bag — a forgiveness-leaning driver, a prototype fairway wood built for tight dispersion, and a blended iron set that trades forgiveness for feedback as the shots get shorter. That’s a different philosophy from a player like Bryson DeChambeau, whose entire bag is built around maximizing speed and launch, or Grant Horvat, whose Takomo-based setup reflects a business relationship as much as a pure performance choice.
