JumboMax JMX ArmLock 21" Putter Grip

The JMX ArmLock 21 from JumboMax® is a slightly oversized grip designed to let you lock the putter shaft securely against your forearm. Available in a pistol-shaped oval or traditional round profile, it promotes a relaxed, tension-free grip for smoother, more consistent putting strokes. Also well-suited for long or “belly” style putters.

Built with a twist-resistant, high-energy transfer core and an ultra-tacky polymer exterior, this grip delivers superior feel and traction in all weather conditions. Its oversized design improves surface contact, eliminates unnecessary wrist movement, and helps stabilize the putter head through impact.
