The largest offering in the SuperStroke line, the Fatso 5.0 maximizes our patented parallel technology and complements a "straight-back, straight-through" putting technique. With over 125 tour players having used SuperStroke technology, our patented grips help the world's best play better every week. The proof: Over $50 million won on Tour. Our parallel technology allows for even pressure in both hands, eliminating added tension in the wrist and forearms. This helps the arms to swing free, further enhancing a pendulum putting stroke. Starting with a light-weight foam under listing, we have added a new high-tech PU material, featuring CrossTraction technology, for improved feel and tackiness. SuperStroke putter grips have a traditional installation process. Simply use double-sided tape and grip solvent to apply. Click on the "how-to" for step-by-step instructions.
