Titleist GTS300 Mini Driver

The Titleist GTS300 is the larger, more forgiving evolution of Titleist's mini driver line — a 305cc head (up from the GT280) built to be a reliable secondary tee option that flies farther than a 3-wood. It features a forged L-Cup face, a deeper, further-back center of gravity for roughly 15-20% more inertia than the GT280, an adjustable rear weight, and Titleist's Fairway SureFit hosel for loft/lie tuning; 13° is the standard loft. The design was shaped heavily by tour feedback — most notably from Justin Thomas and Cameron Young. Thomas was among the first to put it in play, debuting it at the Charles Schwab Challenge in May 2026; Titleist notes he games it on courses that don't demand many 3-woods off the deck, which lets him run a longer 46-inch shaft in his GTS2 driver for extra distance. It launched to the public worldwide on July 23, 2026 at $549 with a featured shaft ($749 with premium shaft options; £499 in the UK).
