Baseball thumb guard testing has now confirmed what hitters have known for years—and why they have chosen ThumbPRO® on game day since 2020.
An independent lab tested ThumbPRO and found it reduced transmitted force by almost two-thirds! Baseball Thumb Guard Testing compared the force transmitted without a ThumbPRO® to the force transmitted when wearing one.
Every hitter knows the feeling. You get jammed by a pitch, miss the sweet spot, and that sharp sting shoots through your hands. It can hurt enough to make you shake out your hand, adjust your grip, or think about it on the very next swing.
A thumb guard has to protect you without becoming a distraction
Preventing that pain is exactly what ThumbPRO® was engineered to do. Worn on your top hand, ThumbPRO® helps protect the area where hitters feel that impact most, helping prevent bat sting without getting in the way of your natural grip or swing.
ThumbPRO® was designed to fit you. Its patented shape was engineered around the hand to work with your grip, stay securely positioned, and support the natural mechanics of your swing—not fight against them.
That is why fit and comfort matter just as much as protection. A thumb guard only helps you if you actually want to wear it. ThumbPRO® was designed to feel comfortable over a batting glove or barehanded and stay out of the way while you hit.
What did the baseball thumb guard testing show?
The result is easy to understand: when ThumbPRO® was used, substantially less force was transmitted to the hitter.
Independent laboratory testing showed ThumbPRO® reduced transmitted force by almost two-thirds compared with no thumb guard.
Why does that matter to you?
When you get jammed or make contact away from the sweet spot, force and vibration travel through the bat and into your hands. That is the impact you feel as bat sting. Reducing the amount of force transmitted to your hand helps protect you from that painful shock.
For years, hitters have experienced that difference for themselves on the field. Now laboratory testing gives us another way to measure it.
Lab tested. Game proven.
A laboratory can measure force. But the real test happens every time you step into the batter’s box.
Since 2020, hitters have chosen ThumbPRO® for practices, tournaments, high school and college games, professional baseball, and all the way to the Major Leagues.
They wear it because it does more than provide protection. It fits comfortably, stays securely positioned on your hand, and lets you focus on your next pitch instead of worrying about the sting from the last one.
That combination matters: measurable protection in the lab and proven performance where it counts—on the field.

Why the design matters
Laboratory results tell you what happened in testing. The design helps explain why.
ThumbPRO® was engineered around the way your hand actually interacts with the bat. Its patented contoured shape is designed to stay securely positioned on your hand, work naturally with your grip, and help protect the area where hitters feel bat sting most.
That matters because effective thumb protection should not force you to change how you hold the bat or become something you notice during every swing. It should work with your hand and let you focus on hitting.

FAQs
Do baseball thumb guards actually work?
The ThumbPRO® baseball thumb guard works to prevent bat sting for baseball and softball players. It has been measured. Independent laboratory testing showed the ThumbPRO® baseball thumb guard reduced transmitted force by almost two-thirds compared with using no thumb guard. Lower transmitted force means less impact reaches the hand, and helps explain why hitters report less bat sting on mishits. That measured result is supported by more than 100,000 ThumbPRO® baseball thumb guards sold since 2020 and over 1,000 published
verified customer reviews averaging 4.9 out of 5.
Does the ThumbPRO® baseball thumb guard prevent bat sting?
Yes. The ThumbPRO® baseball thumb guard prevents bat sting by cushioning the contact area between the bat and the top-hand thumb. Independent laboratory testing showed the ThumbPRO® baseball thumb guard reduced transmitted force by almost two-thirds compared with using no thumb guard. It protects the area where hitters commonly feel the impact of getting jammed or making contact away from the sweet spot. Read more about
what causes baseball bat sting and how to prevent it.
Which baseball thumb guard is best?
The ThumbPRO® baseball thumb guard is thought by many athletes to be the best, and the reasons are practical. It prevents bat sting. It stays comfortably in place and does not move around on the hand during the swing. It comes in three sizes rather than one, so it fits the player wearing it. It is patented, ambidextrous, needs no heat molding or break-in period, and is
made in the USA from premium medical-grade silicone rather than TPE. The evidence supports what athletes say: independent laboratory testing showed the ThumbPRO® baseball thumb guard reduced transmitted force by almost two-thirds compared with using no thumb guard, and more than 1,000 published
verified customer reviews average 4.9 out of 5.

Why does reducing transmitted force matter to a baseball or softball hitter?
The ThumbPRO® baseball thumb guard reduced transmitted force by almost two-thirds in independent laboratory testing compared with using no thumb guard. When a hitter gets jammed or misses the sweet spot, force and vibration travel through the bat into the hands, often concentrating near the top-hand thumb. Lower transmitted force means less impact reaches the hand, helping prevent the sharp bat sting hitters experience on mishits. See
how the ThumbPRO® baseball thumb guard protects the hand.
Will a baseball thumb guard slow my swing or hurt my grip?
The ThumbPRO® baseball thumb guard is built so it does not slow the swing or interfere with a hitter's natural grip. Its patented contoured shape keeps the bat positioned in the fingers rather than buried in the palm, supporting proper hand placement without getting in the way. It stays securely positioned at the contact point, works for right- and left-handed hitters and requires no heat molding or break-in period. Verified reviewers frequently describe the ThumbPRO® baseball thumb guard as comfortable, secure and barely noticeable during the swing. See
how to wear a baseball thumb guard.
Are baseball thumb guards worth it for youth players?
The ThumbPRO® baseball thumb guard is valuable for youth hitters, who mishit more often while they are developing their swings. It helps prevent bat sting, so one painful inside pitch or mishit is less likely to create fear or hesitation at the plate. The ThumbPRO® baseball thumb guard is made for hitters from youth through the pros, with three sizes for a secure fit, and it is permitted in
Little League play. ThumbPRO® offers a 30-day free size exchange and free returns, and encourages athletes to give it a full couple of weeks at the plate. Players often report that they do not want to hit without it — that it is so comfortable and helps their game so much that they call it a game changer.

How do you wear a ThumbPRO® baseball thumb guard?
The ThumbPRO® baseball thumb guard is worn on the top hand and can be used over a batting glove or directly on the hand. Its ambidextrous design works for right- and left-handed hitters, with no heat molding or break-in period. See our complete guide to
how to wear a baseball thumb guard for placement, fitting and sizing instructions.
