The White Hot Versa Double Wide is a double bend face-balanced putter best suited for strokes with minimal arc and face rotation. Our black and white high contrast Versa alignment system has dominated on Tours all over the world. Too often in putting, one of the most essential variables is overlooked – alignment. On a ten foot putt, one degree offline is the difference between a make and a miss. With the encouragement of world renowned putting instructor Phil Kenyon, our Tour proven and patented Versa alignment is back and better than ever. Versa’s high contrast alignment technology highlights the proper face angle from address to impact, allowing you to align the putter throughout your stroke. The black and white contrast lets your eyes key in on the linear designs while highlighting face angle. The lineup features a blend of blades and mallets with our famous White Hot insert and game-changing Stroke Lab shaft. VERSA ALIGNMENT The original White Hot formulation creates incredible feel, sound and performance in one exceptional two-part urethane insert. Versa and the iconic White Hot insert are long time favorites of tour players and golfers alike. They’ve been asking for us to bring these technologies back and we’ve listened. WHITE HOT INSERT The newest generation of our multi-material Stroke Lab shaft features even better performance. By shortening the steel section we reduced the weight by seven grams. We also made it stiffer and more stable for even more consistency in your stroke and your performance. RED STROKE LAB SHAFT The newest generation of our proven multi-material Stroke Lab shaft features even better performance. By shortening the steel section we reduced the weight by seven grams.

The Tri-Hot 5K Double Wide is a wide blade with a crank neck hosel yielding moderate toe hang making it suitable for strokes with moderate swing arc and face rotation. Tri-Hot 5K putters transform the performance of a blade with multi-material front loaded tungsten weighting that improves CG positioning while dramatically increasing inertia. ODYSSEY TRI-HOT 5K DOUBLE WIDE PUTTER FEATURES: High Performance and Tight Dispersion From Stainless Steel FrontTri-Hot 5K is built to improve performance by reducing the amount of side spin on off-center hits. We achieve this through a 303 stainless steel front section that includes the hosel and face area. This material has been finish milled to exact shape and weight, helping to keep the CG forward. This keeps putts closer to the original line, with tighter dispersion, and a greater chance to go in on less-than-perfect strikes. Unprecedented Forgiveness For A Blade and Improved Roll From Tungsten Front WeightsWe’ve precisely positioned massive amounts of tungsten (over 120 grams) behind the face in the toe and heel sections of the club head. We’ve moved the CG forward for improved roll, while also increasing inertia to over 5,000 IZZ. It’s a level of forgiveness that you’ve never seen before in a standard size blade putter. Interchangeable Front WeightsAvailable in aluminum, steel and tungsten, these removable weights allow you to dial in your head weight to your exact preference. Legendary White Hot insertThe most popular insert of all time is back with the original formulation, feel, sound, and performance. Red Stroke Lab ShaftThe newest generation of our proven multi-material Stroke Lab shaft features even better performance. By shortening the steel section, we reduced the weight by seven grams compared to the original Stroke Lab. We also made it stiffer and more stable for even more consistency in your stroke and your performance.

The Ai-ONE Double Wide CH is a wider bodied blade with a crank hosel, providing minimal toe hang that’s best suited for strokes with less face rotation and arc. This putter features our Ai-ONE insert with an aluminum backer and White Hot urethane striking surface and our new SL 90 Stroke Lab steel shaft. All golfers, even the best Tour players in the world, miss the center of face from time to time. And when you lose speed relative to a center hit, the ball doesn’t roll as far as you intended, so you miss more putts or leave them farther from the hole. Now in Odyssey Ai-ONE, we’ve leveraged Callaway’s industry-leading Artificial Intelligence design and super-computing capabilities to create the most advanced insert in golf. The multi-material construction includes unique contours on the back of the face that minimize ball speed losses on off-center hits, and greatly increase the sweet spot. Our revolutionary Ai-ONE urethane insert delivers more consistent ball speeds, even from off-center hits, leaving putts up to 21% closer to the hole. Ai-ONE Insert Designed using Artificial Intelligence, we’ve created contours on the aluminum backer of the insert to promote consistent ball speed across the face. We’ve co-molded a grooved White Hot urethane layer into that aluminum backer for the classic White Hot feel that Tour players and amateurs love. AI Window Our designers and engineers developed a Pnalite window, which is a unique automotive grade polymer, that allows us to showcase the unique topology of the back of the inserts.
