JumboMax STR8
Brilliant grip, have put this on my driver as a test and transformed my shots off the tee. I am now saving a bit of money to put the same grip on every other club.

JumboMax STR8 Tech Non-Tapered JMX UltraLite Series Giant (MEDIUM +5/16") Grips - Black / Blue / Red
JumboMax STR8 Tech™ JMX UltraLite Now With Non-Tapered Grip Technology
The JumboMax STR8 Tech™ JMX UltraLite Non-Tapered Grip combines legendary JumboMax game improvement with a non-tapered profile to maximise lower hand feel and face angle awareness.
A non-tapered grip decreases grip tension. Developed with input and real world testing by some of the world's best instructors and tour professionals.
**Note - The STR8 Tech Non-Tapered JMX UltraLite Series DOES NOT Accept The Cobra Connect™ & Arccos Caddie Smart Sensors**
Sync It Up & STR8 Feel
STR8 Tech is available in three different models to help every golfer take advantage of its non-tapered construction. Its larger lower hand size provides maximum power and delivers unparalleled club face control. Available sizes are, X-SMALL +3/16", MEDIUM +5/16" and X-LARGE +3/8".
Sync up your grip pressure with STR8 Tech, the non-tapered swing grip from JumboMax.
There are benefits to using a grip with a larger lower hand area. The STR8 Tech takes these benefits to the extreme with a super oversize, non-tapered grip surface that’s the same size from top to bottom.
STR8 Tech is the same size throughout the gripping surface, the grip will feel the same whether you choke up or choke down. It’s also a great choice for golfers who use alternative grips such as the 10 finger style, which puts more of your hand’s surface in contact with the grip.
STR8 Tech Vs Tapered
JumboMax STR8 Tech grips have a smaller butt diameter than other JumboMax swing grips, however, the diameter of the gripping surface is the same. For this reason, the butt section of a STR8 Tech grip will feel smaller than the same size in a tapered JumboMax grip, but the lower section of the grip will feel larger.
**Grips Pictured Are MEDIUM +5/16".**
What Bryson Says...
"I'm all about removing variables, and that's exactly what the STR8 Tech does. Think of someone who struggles with a snap hook. More often than not, the issue is an overactive bottom hand. By increasing the overall size of the grip and keeping the size of the bottom hand area consistent, we often see golfers resolve this issue with STR8 Tech because a golfer can finally sync up their grip pressure.
A lot of golfers who come from other sports like baseball or tennis also just love this grip. Why shouldn't they feel the same thing in their golf grip that they felt in other sports?"

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.

Jumbo Max non tapered
I changed these myself with no real problems. They are excellent quality and about the right size for a large glove user. I’d not go back to my old ones… great service too.

Adore Jumbomax STR8 grips
For years I have been troubled with arthritis in my hands and used to get by using thicker Golf Pride New Decade grips but maintaining a strong grip was getting more difficult & obviously trying to grip too hard can have a negative impact. Then I heard about these grips and bought 4 to try and fitted them. Worked a treat and I then fitted them to all my clubs. What a difference, especially for the right hand. Not a cheap option but a great investment.

Jumbomax oversize grips
Ideal for golfers with arthritic hands like me. Easy to grip softly and start playing again like you used to do.
-
Perfect size
Got these fitted on all my clubs. I bow my wrist (attempting a swing like DJ, Bryson etc) and it's perfect for me. It just makes sense having ergonomically sized grips and the non-tapered ones are exceptional. Both your hands are the same size so why would you not have the grip the same diameter all the way along it. Would recommend.

Jumbo max STR8 Tech JMX grips
I have arthritis in my hands and it’s been difficult to grip my clubs without squeezing too hard. Initially I went for new decade multi-compound grips but thought I would try the Jumbo max ones, so I bought 1 initially then another 4 then put them on the full set. I find I don’t need to grip the club as hard as I did with the previous grips so there is less pressure and less tension. It’s early days but I feel much more comfortable and relaxed when gripping my clubs.

First time trying
Really amazing grip - great improvement on my driver consistency. Easy on my hands - considering now for the rest of my clubs. Great service as well - super fast delivery
