Odyssey Ai-ONE Rossie S Golf Putter

Features and Benefits

Golfers of all levels, even the pros, can struggle with not hitting the sweet spot. This results in lost speed and distance, leading to countless score-ruining missed putts. Powered by advanced A.I. and top-tier computing, the Odyssey Ai-ONE Rossie S Putter from Callaway guarantees a superior sweet spot for optimized control and distance.

The Odyssey Ai-ONE Rossie S Golf Putter is a multi-material marvel: intricate contours on the back of the face minimize lost speed from mishits and provide a larger sweet spot. Plus, the cutting-edge Ai-ONE urethane insert will increase your ball speed and put you 21% closer to the hole with each off-center hit - an unbeatable combination!
