I rested it for three weeks. Then I picked up my needles and lasted nine minutes. This is the first thing that held while I was knitting, not after. I finished the cardigan that sat in the basket since November.

A firm support that holds the joint at the base of your thumb and leaves the rest of your hand free.
It takes a minute, and you only measure once.
1. Measure. Wrap a soft tape measure around your palm at its widest point, just below the knuckles, with your thumb relaxed out to the side. No tape measure? A strip of paper or a piece of string works just as well. Wrap it around, mark where it meets, then hold it against a ruler.
Measure your dominant hand, or whichever one is wider. Each order includes a left and a right, so one size covers the pair.
2. Read. Keep it snug but not tight, and note the measurement.
3. Match. Find your number below.
| Small | 7 to 7.5 inches (18 to 19 cm) |
|---|---|
| Medium | 7.5 to 8.5 inches (19 to 21.5 cm) |
| Large | 8.5 to 9 inches (21.5 to 23 cm) |
On the border between two sizes? Take the smaller one. A snug fit at the base of the thumb gives the best support, and the fabric gives a little as it settles in.

The Thumb Stabilizer holds steady for over 11,000 guitarists and other people who were told to use their hands less.
The first squeeze of the day is always the worst one. The joint has to shift and swell before it settles into anything close to normal.

The ligaments at the base of your thumb have stretched out. Every squeeze lets the joint shift a little further than it should.

Your body swells the joint to protect it. That swelling is why the next squeeze hurts more than the last one did.

Not a capo. Not a thumb brace. One firm pad, over the one joint that gives out.
Holds the one joint steady, without locking your whole thumb the way a rigid splint does.

Most people feel it ease over the first two to three weeks of wearing it while they work, not while they rest.

Made for hours of repeated small movements, not for resting an injury for one afternoon.

Recommended by professionals in hand and joint care, not just by the customers wearing it.

How to wear it
The firm pad sits over the base of your thumb, where it meets your wrist.
Snug, not tight. Your fingertips stay bare and your wrist stays free.
Wear it while you do the thing you were told to stop doing.
Everything in your case was built to lower the pressure on your hand. Here is what that costs you.

Blank means it does not do that.
I rested it for three weeks. Then I picked up my needles and lasted nine minutes. This is the first thing that held while I was knitting, not after. I finished the cardigan that sat in the basket since November.

I garden four days a week and my thumb was done by lunch. This fits under my glove. Nobody notices it and I have not had to stop early since.

I play in a covers band on weekends. My fretting thumb gave out after twenty minutes. This is the first support that lets me barre a chord. Not rigid, not bulky, and the joint stays put.

I used to shake my hand out between every hole by the back nine. Last Tuesday I played all eighteen holes and did not set my club down once.

My orthopedist gave me six minutes and told me to find a different hobby. He never asked how I hold my needles. I wear this every evening now and I have not canceled one.

I play three matches most Saturdays in the summer heat, and I sweat through everything. This stayed put through all three and my hand felt normal walking to the car.

I had a padded steering wheel cover and driving gloves before this, and neither one stopped the click when I turned into a spot. This did, the first week I wore it. I parallel parked in one try last Tuesday.

My daughter bought me a compression glove last Christmas and I never told her it did not help. This one does. I picked my granddaughter up off the floor last week without thinking about my hand first.

My hand used to give out halfway through anything with octaves. Last week I played the whole piece without shaking my hand out once. My piano group noticed before I said a word.

I wrung out a dishcloth without stopping for the first time in two years. My husband noticed before I said anything.

This is the first thing most guitarists ask, and it's the right question. It's soft and thin enough to wrap around the base of your thumb without locking your wrist.
A capo and lighter strings lower the pressure your hand makes. A thumb brace locks the joint down so it can't move at all. This holds the joint that the pressure moves through, while leaving your thumb free.
No. It's slim enough that your thumb still wraps around the neck the way it always has. There's no metal and no rigid piece to catch on the wood or the strings.
Hand wash it in cold water and let it air dry. Most guitarists only need to wash it after a few sets.
Some people notice the joint feels steadier the first time they put it on. For most, the ache from a full set of barre chords eases over the first two to three weeks of wearing it regularly.
