Every few years a putter comes along that seems to win people over before it even lands in most markets. The Odyssey TRTL is shaping up to be one of those. It launched in Japan earlier this year, quickly claimed the top four spots on the sales charts, and has become the most requested putter on Tour. So what is all the fuss about? Let's break it down.
A Modern Mallet Built for Stability
The TRTL family is made up of all-new mallet shapes, and the whole idea behind them is exceptionally high MOI. If you're not across the jargon, MOI is basically a measure of how much the head resists twisting when you don't hit the ball dead centre. Higher MOI means your off-centre strikes hold their line and speed better, which is exactly what most of us need on the greens.
Odyssey has achieved this with a clever multi-material build. The body is steel, finished in a premium black PVD that looks sharp at address. The shell is made from lightweight ABS, and the sole is lightweight aerospace-grade aluminium. Using lighter materials in those areas frees up weight that can be pushed out to the perimeter of the head, and that is where the stability and forgiveness come from.

Twin Track Alignment
Looking down at the TRTL, the first thing you'll notice is the new Twin Track alignment. It uses long, uninterrupted lines that make it easy to frame the ball and aim at your target. For golfers who like a strong visual cue at setup, this is a real confidence booster.
The New Ai-Star Insert
Every TRTL model features Odyssey's new Ai-Star insert, and this is where a lot of the performance story lives. It's a dual-layer construction with an aluminium inner layer and a firmer urethane layer on the outside striking surface.
The goal is simple: consistent ball speed across the face and better forward roll, all while keeping that classic Odyssey feel. Because the outer urethane is on the firmer side, you get a responsive feel off the face rather than anything mushy.
Deeper Forward Roll Grooves
Odyssey has also redesigned its Forward Roll grooves. They're now deeper and more aggressive, with a 19° slope, and they work together with the dual-layer design to improve roll on strikes both high and low on the face. In other words, you don't need to be perfect to get the ball rolling nicely.
Sits Square, Every Time
One of the more underrated features here is the all-new sole geometry. The TRTL is designed to sit naturally square the moment you place it behind the ball. Odyssey has refined the rake and camber so the head sits flush to the ground and settles into proper alignment on its own.
That might sound like a small thing, but if you've ever fiddled with a putter at address trying to get it looking right, you'll appreciate how much easier this makes your routine. A more confident setup leads to a more consistent start to every stroke.
Adjustability Like No Odyssey Mallet Before It
This is the feature that really sets the TRTL apart. Four discrete weights sit in the corners of the head, giving you a level of adjustability we haven't seen in an Odyssey mallet before. You can shift the centre of gravity toward the front, rear, heel or toe, and fine tune the amount of toe hang the putter has.
That means the TRTL can be dialled in to suit your stroke rather than you having to adapt to the putter. It's a big plus for anyone who gets properly fitted.
Number One in Japan and Proven on Tour
The results so far speak for themselves. Since launching in Japan, the four TRTL models have stayed the top four selling putters in that market, and they've helped Odyssey climb past 50% total market share there.
On Tour, the buzz is just as strong. Min Woo Lee and recent LPGA Tour winner Yuna Nishimura have both been using the TRTL to improve their putting, along with plenty of players who aren't on Odyssey staff. It's already the brand's most requested putter model on Tour, and Odyssey expects even more to go into play heading toward launch and into 2027.
