Ai-ONE Square 2 Square Max Stripe Putter

The MAX STRIPE is the newest shape in our Square 2 Square line and our most stable with MOI over 6000. This version comes with a bold white paint on the raised center section making it extremely easy to align. With its modern center shafted design this putter balances with the toe up which makes it inclined to stay square to your path throughout your stroke. This putter features our Ai-ONE insert with an aluminum backer and White Hot urethane striking surface which delivers more consistent ball speed across the face and comes with our SL 90 Stroke Lab shaft and Oversize grip.
