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 S neck version comes with a short slant hosel that provides significant toe hang best suited for strokes with more 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.
