Can the Odyssey S2S Tri-Hot Rossie Putter Turn Deniers Into Believers? Spoiler – it did for me!

Zero torque putters are showing no signs of slowing down. They even produced one of the moments of the year on tour in 2025 when JJ Spaun sank a 65ft putt to win the US Open with a L.A.B flat stick. Odyssey has strengthened their position in this is area of putters with a new line-up of square-to-square putters. I took the Tri-Hot Rossie out for testing in France, the results were incredible…

Summary

NCG SUMMARY

Odyssey have doubled down on the success of their Square-to-Square line with the new Tri-Hot Rossie. It is a zero-torque putter that looks, feels, and performs like a true tour-quality product. In a market dominated by LAB Golf, Odyssey’s design team has created something for players who love the stability of zero torque but don’t want to sacrifice traditional looks or feel. Spoiler… its very good.

PROS

• Exceptional feel and distance control
• Premium design
• Excellent alignment aid

CONS

• Slightly unconventional feel for golfers coming straight from a blade

First Impressions

Straight out of the headcover, the Tri-Hot Rossie oozes a premium appeal. The two-tone finish – a deep, rich red paired with matte black, looks bold without being over the top. The white AI face insert pops beautifully at address, and the pistol-style Odyssey grip feels just right in hand. The black Stroke Lab shaft ties it all together nicely.

Some golfers might not love the red, in that case this definitely won’t be the putter for you, but personally, I think it looks very premium.

On-course performance

I tested the Tri-Hot Rossie during a press trip in France, and I’m going to be honest, I wasn’t expecting much. If you have read any of my previous zero torque putter reviews you’ll know I’m a bit of a square-to square putter denier in truth. I like a traditional blade and I’m not a big fan of change. I haven’t particularly enjoyed using them in the past.

But, I have seemingly found the exception. I’m going to big myself up here and state I actually putted really well. My distance control in particular stood out, and the feel off the face was sensational.

With the crosshair-style alignment aid I found it really easy to line-up putts. The head shape feels familiar to any Odyssey mallet user, while still delivering the stable, face-balanced benefits of zero torque. Everything — sound, feedback, balance — feels refined and tour-ready.

In terms of technology and design, this putter is built around zero torque performance. Meaning the head resists twisting through impact. Traditional zero-torque designs often look awkward, as the shaft must enter near the centre of gravity, usually far behind the face. Odyssey’s engineers tackled that head-on by moving mass forward.

They removed significant weight from the back of the putter head and placed a 140g tungsten block close to the face, which shifts 80% of the head’s weight under the top line. As a result, the shaft can now sit much closer to the face. You can feel this all coming together when addressing the golf ball as it feels a lot more comfortable than the oversized zero torque putters.

The Tri-Hot still features Odyssey’s AI Dual Insert. This was a popular inclusion in the AI One Series putters. It includes a variable face thickness for consistent speed and distance control across the entirety of the putter face.

NCG Verdict

Overall, Odyssey might have cracked the code for golfers who love the idea of a stable, torque-free putter but don’t want a funky looking spaceship sat behind the ball. The Tri-Hot Rossie blends traditional looks, premium materials, and advanced engineering in a way that just works.
