Callaway Golf AI-One Putter

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. The Ai-ONE #1 is a traditional heel and toe weighted blade design with rounded bumpers and a crank hosel. The significant toe hang is best suited for strokes with more face rotation and arc. The putter features our Ai-ONE insert with an aluminum backer and White Hot urethane striking surface and our new SL 90 Stroke Lab shaft. 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 our insert. Available in 5, 10, 15 and 20 grams these removable weights allow you to dial in your head weight to your exact preference. Designed using Artificial Intelligence, we've created contours on the Aluminum backer of the insert which we co-mold to a White Hot Urethane striking surface to promote consistent ball speed across the face with the classic White Hot feel that Tour players and amateurs love. A lightweight steel shaft with 20-30 grams (depending on the grip) of counterbalance weight in the butt end. This is an evolution of our Stroke Lab weighting that will appeal to even more golfers.
