Engineered for ArmLock putting

The JumboMax JumboFlat 17 is designed for players who prefer the ArmLock style. Its extra-wide, flat surface helps you align and stabilize your stroke, delivering a repeatable feel from address to roll. The grip pairs a substantial weight with a tactile surface, giving you a confident connection with the club head.

Popular among tour players and enthusiasts alike, the JumboFlat 17 has been associated with elite results in the hands of champions.
