Odyssey TRTL Putters: An Overview of the New Mallet Series

Odyssey is expanding its Mallet lineup with a new family of Putters: the TRTL and the larger TRTL Max. Both models combine a distinctive alignment aid with a new face insert and a design that, according to the manufacturer, is engineered for stability and forgiveness. The two shapes each emphasize different aspects—ranging from a mid-Mallet design to a Square-to-Square concept.

Two Shapes, Two Approaches

The Odyssey TRTL is a mid-Mallet designed for a clearly visible alignment line and a high moment of inertia (MOI). It is available with three hosel options: Crank Hosel, Double Bend, and S Neck. The model names alone do not indicate which one suits your putting stroke—factors such as alignment, face rotation, and personal feel are also important.

The Odyssey TRTL Max is larger in size and designed for an exceptionally high MOI. The Square-2-Square version utilizes a zero-torque concept. It is intended to reduce face rotation during the putting stroke and help golfers keep the clubface as square as possible to the putting line. This is the design’s objective, not a guarantee of a specific result.

Odyssey also offers longer and heavier Cruiser variants for the TRTL Max, as well as a Broomstick model. According to the spec sheet, the latter features a 445-gram head, an SL-200 shaft, and a two-piece grip. For the Cruiser versions, a heavier SL-140 shaft and 36- and 38-inch configurations are listed.

Twin Track and Ai-Star: Alignment and Face Feel

A key distinguishing feature of the TRTL family is the Twin Track lines. They run long and continuous across the head and are designed to make aiming easier—especially for players who like to use a clearly visible line as a guide.

Another new feature is the Ai-Star insert. Its construction combines an aluminum core with a firmer urethane layer on the face. According to Odyssey, this combination is designed to make ball speed more consistent across the face and promote the ball’s forward roll. The grooves of the Forward Roll design are deeper and feature a 19-degree angle. The manufacturer describes the feel at impact as firmer and more direct.

Multi-material head with adjustable weighting

The clubhead is made of multiple materials: The body is constructed of steel with a black PVD coating; it also features a lightweight ABS shell and an aluminum sole. According to Odyssey, the weight distribution around the edge of the head is designed to provide greater stability on off-center Puts.

Four weights at the corners of the head offer further customization options. Depending on the configuration, the center of gravity can be shifted forward, backward, toward the heel, or toward the toe. This is also intended to allow for fine-tuning of the toe hang. According to the spec sheet, additional weight kits are available separately.

The sole has also been redesigned. Revised geometry featuring rake and camber is designed to ensure that the Putter naturally lies flat and aligns Square when placed behind the ball. This can support a more consistent setup at the ball; however, how helpful it is in individual cases also depends on the setup and personal alignment.

Who might be interested in the Odyssey TRTL Putter?

The TRTL could be of interest to golfers who prefer a Mallet-style putter with clearly visible, long alignment lines. If you’re looking for a larger head shape and a Square-to-Square design, check out the TRTL Max. The weight options offer additional customization possibilities—especially if you want to fine-tune the center of gravity and toe hang.

The different neck styles and head and shaft configurations make it worthwhile to compare options before purchasing. However, the information provided here does not link the variants to specific Putt strokes. If you’re unsure which setup suits your stroke, a test or a Putter fitting can help.

Tour Interest and Initial Feedback

Odyssey reports a strong start for the TRTL series in Japan: there, the four models offered have been the best-sellers since their launch; the brand’s market share has exceeded 50 percent. These figures come from manufacturer and media reports and do not represent an independent market analysis. Among the players using the Putter are Min Woo Lee and Yuna Nishimura.

Eric Stubben, head of putter development at Odyssey, says in a press release regarding the design: “Conceptually, it maximizes MOI—and we believe in that.” He also emphasizes that using the putter is intended to enable more consistent ball speed and better distance control across the face.

Price and Availability

According to Odyssey’s announcements, the Odyssey TRTL family is available for pre-order; the retail launch is scheduled for November 6, 2026. The listed prices are 399 euros for the TRTL models and 439 euros for the TRTL Max Square 2 Square.

Mid-Mallet or Square 2 Square?

With the TRTL and TRTL Max, Odyssey is introducing two different Mallet shapes that share a range of technologies: Twin-Track alignment, Ai-Star insert, multi-material construction, and adjustable weights. The Mid-Mallet offers three neck options; the larger TRTL Max, with its Square 2 Square design, is aimed at golfers who want to reduce face rotation.

The best way to determine whether the alignment, the firmer feel at impact, or the adjustable weighting suits your game is to try them out. The advertised performance features describe Odyssey’s design goals—they are no substitute for individual testing.
