AT90 Long Putters (Left Handed)

The AT-90 mallet long putter is the newest edition to the Thomas Golf line.  While it shares the red aluminum striking plate, square weight bars and black stealth finish of the AT-91, the weight distribution of this putter makes for a dynamically different feel.  The square weight bars of the AT-90 are centered symmetrically just on the perimeter of the sweet spot.  This allows for a more solid impact with the golf ball, resulting in a better roll and feel when making your putt.  The square bars are also useful by allowing you to frame the ball within the bars, providing extra alignment when looking down at your putt.


 The AT-90 has achieved the most extreme MOI by combining an extra-light aluminum body with heavy weight bars placed on the perimeter of the putter's sweet spot. The weight bars are the first ever with flat tops and sides to further improve alignment of the putt.

 This AT-90 model is center-shafted for greater stability during the stroke. It features a machined face and high grade CNC-milled red aluminum striking plate insert. The extended mallet design offers a little extra heaviness for golfers who prefer more weight than traditional style putters.

 Alignment Technology

 Thomas Golf's putter alignment systems are the result of extensive studies in visual perception and application of expert design methods. The wide channel and golf's first squared weight bars frame the ball and the 3-dimensional visualization provides excellent visualization and guidance for your putt. The channel works in synergy with the bi-level aiming indicator to ensure proper direction and that your head is correctly positioned over the golf ball. On the upper surface in front of the white directional line is a distinct white dot that aligns to let you know when your eye is directly over the ball.

 The squared silver weight bars are much heavier than the black aluminum of the body, shifting weight placement to the far perimeter of this face-balanced putter for an extremely high MOI, creating even better forgiveness and truer roll.


The AT-90 putter is treated with a multi-step black stealth finish to eliminate glare and provide long lasting durability.
