Odyssey EXO White Hot Putter Review

Odyssey has long led the way in putter design and technology and continues to do so with the EXO. For players with arching strokes or that prefer a mallet head, the EXO brings two former Odyssey technologies together in one putter that is not only modern, but noticeably consistent and forgiving.

The White Hot Microhinge insert in the EXO combines White Hot Insert Technology from the early 2000s with Microhinge Technology from the O-Works putter series of 2017 to create Odyessey’s most optimally performing face to date. While some players have complained that the original White Hot insert was too soft, the White Hot insert in the EXO is slightly firmer giving players increased feel and enhanced sound feedback upon impact. Microhinge Technology helps to get the ball rolling more quickly than other putters. By reducing the number of contact points with the ball at impact, the skidding effect is greatly reduced, helping putts to stay on-line and roll true.

The head construction in the EXO utilizes different materials, strategically placed throughout the head to optimize stability and increase MOI for maximum forgiveness. The black material on the perimeter of the head is heavier 17-4 stainless steel while the red center sections are made of 6061 milled aluminum which is 1/3 lighter. By keeping the majority of the weight on the outside of the head, the EXO delivers maximum forgiveness across the entire face.

The Indianapolis, Rossie, and Seven mallet head models are all derived from previously popular Odyssey head designs and allow players a variety of options. Each model is also available in either a toe-hang of face balance option allowing players to further match a putter to their stroke.

We tested the Odyssey EXO putter line, which combines the legendary White Hot insert with the company's Microhinge face technology for improved roll. Here's what we found: 

Feel and Sound 
The EXO putters provide the classic soft feel and sound of the original White Hot insert, while the Microhinge face adds a slightly higher-pitched impact sound compared to previous Microhinge designs. The feel is soft yet solid at impact. 

Roll and Distance Control 
The Microhinge face promotes immediate forward roll for more consistent distance control. Testers found the EXO eliminated the skipping sensation often seen on longer putts with previous inserts. The combination of the White Hot feel and Microhinge roll instilled confidence in controlling speed. 

Stability and Alignment 
The multi-material construction of the EXO heads, with weight concentrated in the perimeter, creates an incredibly high MOI for stability and forgiveness. The large mallet heads, like the Indianapolis model, feel extremely stable through the stroke. The contrasting red aluminum framing helps with alignment and getting the face square at address. 

Customization Options 
The EXO line is available in three head shapes - Indianapolis, Rossie, and #7 - each offered in both slant neck and double bend shaft configurations to suit different stroke types. Grip options include the Odyssey Pistol grip or SuperStroke Mid Slim 2.0.Overall, the Odyssey EXO putters provide the classic White Hot feel golfers love, combined with innovative Microhinge roll technology and high MOI stability in a premium, customizable package. The EXO line represents a successful meeting of Odyssey's most iconic insert and latest performance innovations.
