Odyssey S2S Tri-Hot Putter Review : The new zero-torque gold standard?

When it was first revealed in November 2025, Odyssey's new Square 2 Square Tri-Hot putter range promised big things.

Marketed around the idea of 'pushing zero-torque forward', the eye-catching new line, with its bold red and black colour scheme, was introduced as a genuine step forward in a segment of the market already full of expensive, experimental models. 

Every putter brand, from L.A.B Golf to TaylorMade, is locked in an arms race to perfect the zero-torque formula and make it accessible for more golfers. With the Tri-Hot, the brand truly believes it has set itself apart from the pack – which explains why it has already superseded the Ai-ONE Square 2 Square as the flagship model in Odyssey's putter range after barely a year.

So what's new about the Tri-Hot range, what sets it apart from last year's model, and most importantly, should you choose it if you're searching for the best zero torque putter to suit your game?

We took it on the course to find out how it stacks up to the best putters on the market.

Looks and features

While Ai-One Square 2 Square felt like something of a tentative step into the zero torque category for Odyssey, the Tri-Hot feels like a far bolder statement of intent from both an aesthetic and technological standpoint.

The distinctive red and black colourway stands out from the pack at first glance, of course, but the Tri-Hot is a also a far more progressive entry into the zero-torque segment from a technical standpoint compared to its predecessor, introducing a number of developments that Odyssey hopes will bring zero-torque technology – something that can be tricky for everyday players to get used to – into the hands of more golfers.

The key change introduced with the Tri-Hot, lending the range its 'pushing zero-torque forward' tagline, is Odyssey's decision to move the centre of gravity in the putter forward towards the face. Made from a combination of aluminium, steel and a huge 140g of Tungsten, most of the heavier materials are placed as far towards the front of the putter as possible, with the back of the putter feeling noticeably lighter as a result.

In practice, this has allowed the brand to move the shaft forward on the putter head in turn, making for a more natural feel when looking over the ball compared to traditional zero-torque putters that have their shafts more centred in the club head.

Leaning once again into Callaway's much-loved theme of AI-developed face technology, a new AI-DUAL insert also debuts in the Tri-Hot range, made with a soft outer layer and a firm inner layer with varying thicknesses that you can actually see in the form of the wavy, inconsistent line that sits just behind the face. It's a cool visual display of technology, but might look a little bit odd if you don't know exactly what it is you're looking at.

The goal here is to keep the soft feel Odyssey's insert putters are so well-loved for, while creating a more consistent roll on off-centre strikes.

To aid this further, Odyssey have also engineered the insert with a much more aggressive take on the grooves in the insert. Cut to a 19° angle, the idea here once again is to improve forward roll.

Like the Ai-ONE S2S range, the S2S Tri-Hot line comes in a variety of choices from Odyssey's most beloved putter profiles. We tested the Jailbird, however the longer Jailbird Cruiser, the mid-mallet #7, and half-moon Rossie shapes are all available.

The final major change that we have to come back to is, of course, the colour. This is easily Odyssey's most visually distinctive putter range for a good few years, painted in a deep, rich red offset a thick black topline and subtle white accents. In the case of the Jailbird, the red and black combine to form a two-tone Versa pattern to further aid alignment. 

Will the red be to everyone's taste? Absolutely not, especially if you have a more traditional mindset towards allowing colour into your bag. However Odyssey have done a good job of balancing the red with the more neutral black to ensure it doesn't look too gimmicky, and while the Tri-Hot looks a little shouty at first glance, once you get accustomed to it the Tri-Hot actually blends into the bag surprisingly well.

Feel & performance

The key conundrum Odyssey set out to solve with the Tri-Hot is the question of how to make zero-torque putters feel more natural to golfers who have sometimes spent decades using a more conventional putter. 

With zero-torque putters generally having a more centred shaft placement, most brands have compensated for this by engineering their putters with a ton of forward press, creating a feeling at address that's often deeply off-putting for newcomers.The Tri-Hot addresses this very effectively. 

The forward-weighted CG, in addition to the change of shaft position this allows, makes for a feeling standing over the ball that'll be much more familiar and comfortable to players taking their first steps into the zero-torque realm. Put simply, it's the most 'normal' feeling zero-torque putter we've tested to date.

Fans of the typical feel of Odyssey's putters will find a lot to love in the Tri-Hot. The AI-DUAL insert has the added cushion we've come to expect with Odyssey's putter inserts over the years, and Odyssey have done well to create a soft, balanced feel without sacrificing too much feedback. 

Getting the ball rolling well and on-line will, of course, primarily always come down to the player. But the combination of the zero-torque technology and the face insert with its aggressive grooves ensure that the putter is doing everything it can to assist you at every step.

The question of whether or not more golfers should be investing in a zero torque putter is one that has become a matter of increasing debate as the technology becomes more and more mainstream. 

But while it's clear that not everyone should be forcing themselves into a ZT option simply for the sake of it, there's also a clear gap in the market for a zero-torque putter that promises a more accessible, user-friendly experience to those who want the feel of a more conventional putter. 

The Tri-Hot is exactly that, creating an experience that simply feels far more natural and approachable to everyday players while delivering the numerous benefits that zero-torque putters can have to those who struggle with squaring the putter face consistently.

There is, of course, the small matter of price. At £499 (or £529 for the Jailbird Cruiser), the Tri-Hot is comfortably Odyssey's most expensive flagship range. Most retailers are stocking the new line for under £450, however, and compared to zero-torque models from the likes of L.A.B., TaylorMade and PXG, the price tag is fairly run-of-the-mill.

As such, if we came across a player curious about whether or not a zero-torque putter is right for their game, this is overwhelmingly the model we'd encourage them to try first, and that's about the greatest compliment we can give it.
