Description

Callaway Square 2 Square TRI-HOT Rossie Putter

A breakthrough in Zero-Torque putter design, Odyssey's all-new S2S TRI-HOT multi-material construction advances the Zero-Torque category by eliminating shaft lean and positioning the shaft closer to the face than other putters in it's class. The S2S TRI-HOT Rossie features Odyssey's most advanced insert ever, the two-layer urethane Ai-DUAL design delivers consistent ball speed across the face and improved forward roll.

Features & Benefits

Multi-Material Construction
By strategically using Aluminum, Steel, and over 140 grams of tungsten we have been able to design a “Zero Torque” putter with more than 80% of it’s weight under the topline and allowing for our forward CG and hosel position.


Ai-DUAL Insert
Designed using Artificial Intelligence, this dual-layer urethane insert has a soft outer layer and a firm inner layer delivering not only consistent ball speed across the face, but also enhanced forward roll up and down the face and amazing feel.


New F.R.D. Groove Design
This new Forward Roll Design groove design is deeper and more aggressive with a 19° slope it works in conjunction with the dual layer design to improve forward roll up and down the face.


New Pistol Plus Grip
We surveyed the most popular grips used on Tours around the world and looked for commonalities and opportunities to improve on those designs. The result is a mid-sized pistol grip with crisp edges that allow it to fit comfortably in your hands and give you a better awareness of where the putter face is throughout your stroke. 


Black SL 120 Shaft
This black PVD shaft, developed based on Tour player feedback, is heavier and stiffer than our SL 90 and ideally suite for this style of putter.
