New! — The JumboMax STR8 Tech™ Non-Tapered Grip. Combines legendary JumboMax game-improvement with a non-tapered profile to maximize lower hand feel and face angle awareness. Decreases grip tension. Developed with input and real-world testing by some of the world's best instructors and tour professionals.

The STR8 Tech™ grip also features a recessed cavity which will accommodate the Cobra Connect™ and Arccos Caddie Smart Sensors available here.

JumboMax Grips simply fit your hands better for increased distance, better accuracy and more solid ball striking. Our patented design and larger diameter provides a superior “Finger-Palm™ grip” that is revolutionizing the game of golf. Independent tests by GolfTest USA and Golf Etc. showed that in nearly every category tested, from club head speed, launch angle, side spin, back spin to carry distance, JumboMax Grips outperformed standard golf grips. Once you try them you'll never want to play a "skinny" grip again.
