The Jailbird Nano is the smallest Jailbird in our line. A request from Tour this head is 5% smaller than the Jailbird Mini, but with the same overall shape and Versa alignment. This DB version comes with a Double Bend shaft making this putter face balanced and best suited for strokes with minimal arc and face rotation and features our Ai-ONE insert with an aluminum backer and White Hot urethane striking surface and our SL 90 Stroke Lab steel shaft.
