The performance characteristics of JumboMax Grips are achieved through a twist-resistant, high-energy transfer core, while the ultra-tacky, shock-absorbing outer layer enhances feel and playability in a variety of weather conditions.

The Patented JumboMax grips are designed to provide you with:

  • Better Control & Accuracy
  • Faster Clubhead Speed
  • Increased Distance
  • More Confidence
  • Shock Absorbing Technology

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 can quickly and dramatically improve the way you play 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 beat standard golf grips. Once you try them you'll never want to go back to a "skinny" grip again.

Patented. Conforms with USGA Rules.

5 years in development and testing, JumboMax Grips can make an immediate improvement in your golf game.

In head-to-head testing by Golf Etc. of America, and GolfTest USA, golfers increased their driver carry distance by an average of 10 yards, reduced slice spin, increased ball speed, improved launch angle and gained accuracy.

In 73% of categories tested, JumboMax Grips beat standard grips!

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.

    Jumbomax medium

    Posted by Pete Croft on 22nd Dec 2021

    Having large hands I’ve always preferred a bigger grip. I’ve tried a few over the years but this the best by a long way, tried on my driver first then did the rest. Feels really secure and slightly tacky. Recommend.

    Jumbomax +5/16

    Posted by Geoff B on 26th Oct 2021

    I have been playing golf since the late 50’s. Holding clubs with regular grips had become a problem. The Jumbomax grips solved the problem and I have regained confidence throughout the bag - and I am hitting the ball straighter! Adore Golf do a far better job of explaining sizing than other suppliers.

    Amazing grip

    Posted by Paul on 19th Aug 2021

    Love these Jumbo Max Lite. Didn't take long to get used to them and feel I have more control over the driver face. I use single plane and thought I'd try grips a bit smaller than Bryson's :) glad I did.

    There are many reasons to try super jumbo grips, perhaps to bring out your inner Bryson ? For me arthritis developing in the fingers of my right hand. The Jumbomax grips are absolutely superb they allow a confident yet comfortable grip reducing the grip tension dramatically both in the hand and forearm. I can now manage a whole bucket of range balls whereas before after 20 or so I was done. Only thing stopping a 5 star rating is the cost, anything over £10 for a grip is a bit steep.

    Different but amazing

    Posted by Mr Lee Harrison on 1st Mar 2021

    If your hesitant about trying these don't be. Best thing I've done is kit my bag out in these. Feel amazing and my ball striking feels so much better. Feels like I have a lot more control with my swing.

    JumboMax Medium

    Posted by Gary Aitchison on 2nd Feb 2021

    This was the first time I bought this. My bad shot is a pull or a hook. With this grip it encourages you to place the club in the life line of your palm. Thus making it more difficult to turn the club over at impact. The grip was very light and the made from high quality material. I re-gripped the club my self and found it to be trickier than a regular grip to get on. It requires a bit of muscle. That said I am very happy with the product and would definitely recommend to anyone thinking about purchasing it or one like it. I wear a large glove and the medium size was perfect.
