The Odyssey Tri-Hot Square 2 Square Jailbird is a landmark evolution in Zero-Torque putter design. The all-new S2S TRI-HOT multi-material construction eliminates shaft lean and positions the shaft closer to the face than any other putter in its class, making it easier than ever to set up square, aim square, and stay square — without needing a forward press. Built around the iconic Jailbird mallet head shape that Tour players and amateurs love, this putter combines cutting-edge engineering with outstanding feel, delivering unmatched stability and precision on every putt. It comes complete with a headcover.
Odyssey's all-new S2S TRI-HOT multi-material construction represents a genuine breakthrough in the Zero-Torque putter category. By strategically combining ultra-light aluminum, steel, and over 140 grams of heavy tungsten, engineers were able to shift the centre of gravity far enough forward that the shaft enters the head at the topline — entirely eliminating the need for shaft lean. With more than 80% of the head weight sitting below the topline, the forward CG and hosel position work together to let the golfer adopt a more natural, intuitive, and comfortable address position. The result is a putter that is better balanced, more ergonomic to set up, and far easier to keep square through impact — removing one of the biggest barriers to success with Zero-Torque designs.
The Ai-DUAL Insert is Odyssey's most advanced insert technology ever brought to market. Designed using Artificial Intelligence, the dual-layer urethane construction features a soft outer layer and a firm inner layer that work together to deliver not only consistent ball speed across the entire face, but also enhanced forward roll both up and down the face on every putt. The AI-driven face geometry optimises the contours of the inner aluminum backer so that even off-centre contact produces a predictable, repeatable result. The overall feel at impact is described as remarkable — responsive yet soft, giving the golfer the confidence to commit to every stroke.
The new Forward Roll Design (FRD) Groove is deeper and more aggressively machined than previous Odyssey groove designs. Operating at a precise 19° slope, the groove is engineered to work in direct conjunction with the dual-layer Ai-DUAL insert construction to maximise forward roll across the full height of the face. Improved forward roll means the ball transitions from sliding to rolling sooner after impact, producing a truer, more consistent ball path and reducing the risk of skipping or bouncing on the putting surface. This combination of groove geometry and insert technology is what sets the Tri-Hot Jailbird apart from conventional mallet putters.
The new Pistol Plus grip was developed after surveying the most popular grip styles used by professionals on Tours around the world, identifying common preferences and opportunities for improvement. The result is a mid-sized pistol-style grip featuring crisp, well-defined edges that allow it to sit comfortably and securely in the hands. The defined shape provides the golfer with a heightened sense of where the putter face is pointing at all times throughout the stroke — an important element in building consistent, repeatable alignment. Its moderate size suits a wide range of hand sizes and grip styles.
The Black SL 120 shaft is a purpose-built component developed in direct response to Tour player feedback on the requirements of Zero-Torque putter designs. Finished in a premium black PVD (Physical Vapour Deposition) coating, it is noticeably heavier and stiffer than Odyssey's previous SL 90 shaft. The additional weight and rigidity of the SL 120 complement the forward-weighted head design, helping to create a balanced feel that promotes a smooth, controlled putting stroke. This shaft is specifically calibrated to enhance the performance characteristics of the S2S TRI-HOT head — it is not simply adapted from another model.
The Jailbird is one of the most recognisable and beloved head shapes in Odyssey's storied lineup — a classic mallet profile that has earned its reputation on Tour and in the bags of golfers of all skill levels. In the S2S TRI-HOT configuration, the Jailbird's distinctive shape is paired with a face-balanced 90° Up toe hang, meaning the head naturally wants to stay square to the arc throughout the stroke. The striking visual presence of the mallet design at address provides strong alignment cues, helping golfers aim confidently and commit to their line. The Jailbird TRI-HOT is the perfect blend of heritage design and next-generation technology.
