A Rookie’s Bag Full of Secrets
Michael Brennan has turned heads on the tour with a bag that looks more like a testing lab than a standard setup. While many players stick to retail models, the American rookie is running a fleet of specific prototypes and custom shafts. According to Golf Monthly, this unique configuration played a major role in his immediate success at the Bank of Utah Championship (where he finished top-tier). The gear he carries represents a precise blend of high-end tech designed for one specific player. Fans and analysts alike are taking note of how a pro can mix standard irons with rare fairway woods to find an edge.
The Full Breakdown of His 2026 Clubs
The driver is the first piece of the puzzle. Brennan uses a Titleist GT3 driver with an 8° head. This head is combined with a Project X HZRDUS Silver TX 70 shaft.
Moving to the fairway, the setup gets even more interesting. He has a Titleist GTS Prototype fairway wood set at 15°. Golf Monthly describes this club as essentially a 3-wood equipped with a Project X Titan Yellow TX 80 shaft. It’s rare to see a prototype 3-wood in a main bag, but Brennan is clearly chasing specific numbers. His long game doesn’t stop there. Brennan uses a Titleist GTS3 7-wood set at 21°. A Project X Titan Yellow TX 80 shaft is also found in this club, similar to his 3-wood. The consistency in shaft choice for his woods suggests a very specific feel requirement.
For the long irons, he carries a Titleist T150 3-iron. The 3-iron is fitted with a Project X HZRDUS Black TX 105 HY shaft. This mix of a hybrid-style shaft in an iron head shows a modern approach to distance and launch. From the 4-iron down, the bag shifts to a classic blade feel. Brennan uses Titleist 620 CB irons from 4-iron to 9-iron. The 4-iron to 9-iron feature Project X Rifle 6.5 shafts. This is a very stiff, traditional shaft choice that demands a fast swing speed.
The wedges follow a similar pattern of high-end customization. Brennan uses Titleist Vokey SM11 wedges. The 46° and 54° wedges contain Project X Rifle 6.5 shafts. The 60° wedge comes with a True Temper Dynamic Gold Tour Issue S400 shaft, states Golf Monthly. It’s a mix of shaft types that indicates he tweaks each wedge for a specific bounce or trajectory. On the greens, he relies on a Scotty Cameron Circle T TG6 Prototype putter. This is a putter you won’t find in a store, marking him as a true insider with access to top-tier gear. Finally, he plays a Titleist Pro V1 golf ball. Every single item in the bag, from the driver to the ball, is sourced and verified by Golf Monthly reporting.
The combination of a GTS Prototype 3-wood and a Circle T putter means Brennan is engineering his game. Most amateurs and even many pros use what they buy off the shelf. Brennan, however, is utilizing equipment that likely isn’t available to the public yet. This access allows him to fine-tune launch angles and spin rates that retail clubs simply cannot match. The switch to a 21° 7-wood with a heavy 80-gram shaft is a bold move. It suggests he needs help getting the ball in the air from the fairway without sacrificing distance.

Furthermore, the use of different shafts in his wedges is a telling detail. Matching the 46° and 54° with Rifle 6.5s while switching the 60° to a Dynamic Gold S400 implies he wants a different feel on his highest-lofted shot. This level of detail often separates the good players from the great ones. The fact that he runs a T150 3-iron with a hybrid shaft alongside traditional CB irons shows he prioritizes function over a uniform look. He doesn’t care if the shafts look the same; he cares if they perform. This pragmatic approach is exactly what a young pro needs to survive on tour.
