What Bryson Says...

"I used these grips to win the 2020 U.S. Open. They're everything I could want in a swing grip. They're simply the best of both worlds and they help me max out the distance with every club in my bag.

I just love the way the UltraLites feel. They're firm, stable and don't tear up my hands even with all the hours of practice I put in."

JumboMax® Grips are designed to fit your hands better for more solid ball striking. Our Finger-Palm™ technology places the grip in the strongest, most stable part of your hand while promoting a relaxed grip on the club for a more fluid and powerful swing.


JumboMax Grips eliminate tension for faster clubhead speed. Golf instructors universally agree that the fastest way to ruin a good golf swing is by gripping the club too tightly, or by increasing grip pressure during the swing, which prevents the club from releasing at impact. Our Finger-Palm technology instantly gives you a more secure hold on the club, so you don't feel the need to squeeze. You'll relax your grip on the club freeing your hands and arms to release the club naturally, giving you the fluid, effortless and powerful swing you need. You'll find it easier to keep the clubface square longer through impact for straighter, more powerful shots.

How do JumboMax compare to standard grips?

The golf industry does have a standard for measuring grip sizing on non-putter grips. Measuring 2" below the grip end cap, the diameter of the grip is recorded.

The following chart compares the diameter 2" below the grip end cap for various grip sizes.


Play and practice longer with less shock on your joints.

JumboMax Grips outperform standard grips for distance and accuracy and have the added benefit of being extremely shock-absorbing. If you experience pain during or after golf or have arthritis, you will really appreciate our super-oversized, shock absorbing technology.

Yes, these grips are for you.

From novices to advanced players, everyone can benefit from the secure, yet relaxed grip provided by JumboMax Grips. They will quickly and dramatically improve the way you play the game of golf adding to the enjoyment of your game.
