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 CH version comes with a crank hosel that provides minimal toe hang best suited for strokes with less face rotation and arc and features our Ai-ONE insert with an aluminum backer and White Hot urethane striking surface and our SL 90 Stroke Lab steel shaft.
