The Ai-ONE 24S is a modern mid-mallet featuring a surprisingly high MOI design in an all-new Odyssey shape. Inspired by classic cars, a new bold alignment line pointing directly down the target line.

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 Ai-ONE lineup has been an incredible success for regular golfers and on Tour where it continues to win. Now we’re adding exciting new offerings with the Wing Back, 24, and 2-Ball Jailbird.

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 AiONE urethane insert delivers more consistent ball speeds, even from off-center hits, leaving putts up to 21% closer to the hole. 

To achieve this unmatched level of performance, we made the back of the insert out of aluminum and added a White Hot Urethane to the striking surface for the iconic White Hot feel that millions of golfers love. These enhancements provide incredible feel, speed control, and consistency in a design that’s changing the face of putting.

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 Panlite window, which is a unique automotive grade polymer, that allows us to showcase the unique topology of the back of the insert.
