It holds the thumb joint steady and leaves the rest of your hand alone.

A molded panel sits directly over the joint at the base of the thumb and holds it in place through the movements that aggravate it — pinching, twisting a lid, turning a key. Support runs up the thumb rather than stopping at the base, and a wrist strap anchors the whole thing so it doesn't rotate or slide as you use your hand.

Your palm and four fingers stay uncovered. You can grip, pinch, type, and hold a cup with the brace on.

• Contoured CMC support pad. A molded panel over the base-of-thumb joint keeps it steady through pinching movements.
• Extended thumb post. Support continues up the thumb instead of ending at the base, for more stability where it counts.
• Anchored wrist strap and palmar bar. An adjustable hook-and-loop closure locks the brace in position so it won't spin or slip.
• Nothing across the palm or fingers. Fine movement, pinching, and gripping stay fully available.
• Lightweight and low-profile. Thin enough to forget you're wearing it, which is what makes all-day use realistic.

Clinicians' Choice designated. Backed by a 60-day money-back guarantee, so you can wear it through a full stretch of ordinary days and send it back if it isn't for you.

One size, adjustable.

There is nothing to measure and no chart to read. The hook-and-loop wrist strap adjusts to fit, and the brace is made to suit either hand.

1. Position it. Slide your thumb through the opening so the molded pad sits squarely over the joint at the base of the thumb, with the palmar bar resting across the heel of your hand. Get the pad placed before you fasten anything. If it sits too high on the thumb or too far toward the wrist, the support lands in the wrong spot.
2. Anchor it. Wrap the strap around your wrist and press the closure down, working outward from the middle so the brace sits flat.
3. Check the fit. Snug, not tight. Your thumb should feel supported but your fingers should move freely, with no pinching, throbbing, or tingling. If you see marks on your skin after wearing it, loosen the strap a notch.

If it rotates while you wear it, tighten the wrist strap rather than repositioning the pad mid-task. The strap is what stops the brace from sliding, and the pad only works while it's sitting over the joint.

What matters is consistency.

The brace works by taking load off the joint during the movements that irritate it, so wearing it through your ordinary day is what builds results.

Here's what our customers report:

• Days 1–2: Immediate steadiness while pinching and gripping, and a little less soreness at the end of a long day. The brace itself takes a day or two to stop feeling unfamiliar.
• Weeks 2–3: Less stiffness first thing in the morning, and the tasks that used to sting — jar lids, keys, buttons — starting to feel manageable again.
• Weeks 4–6: Most people hit their stride here. Steady daily support shows up in how the thumb feels between wears, not only while the brace is on.
• Ongoing: Continued use maintains results. Stopping puts the full load back through the joint, and the old soreness tends to creep back over several weeks.

One note: Our brace is a wearable support, not a medical device and not a treatment or cure for arthritis, osteoarthritis, tendinitis, or any other condition. If you've been diagnosed with a joint condition or you're recovering from an injury or surgery, check with your doctor before use — and stop wearing it if you notice numbness, tingling, or increased pain.

What is it made of?

A durable blend of aluminium alloy, NBR rubber, silicone synthetic leather, and TPU plastic. The alloy holds the shape of the support, the TPU and silicone leather take the abrasion of daily wear, and the rubber sits against your skin.

Allergy & sensitive skin information

• No natural rubber latex. The rubber used is NBR, a synthetic.

How do I care for it?

Machine washable. Close the hook-and-loop strap on itself first so it doesn't catch, wash cool on a gentle cycle in a mesh laundry bag, and lay it flat to dry in the shade.

Skip the bleach, the fabric softener, the tumble dryer, and the iron. Heat is what warps the plastic and softens the adhesive holding the panels together.
