Comfort Cool Thumb CMC Restriction Splint - Black, Left Hand, Large (NC79566)

The Thumb Brace Recommended by Physical & Occupational Therapists

If you're living with CMC joint arthritis, basal joint pain, tendinitis, or repetitive use strain, the Comfort Cool CMC Thumb Brace Restriction Splint is the solution trusted most by medical professionals — and loved by thousands of patients.

Why Patients & Providers Choose Comfort Cool:

The CMC (carpometacarpal) joint sits at the base of your thumb and is one of the most commonly affected joints in hand arthritis. Everyday tasks — opening jars, gripping a pen, turning a key — can become painfully difficult. This brace is specifically engineered to address that.

Patented Thumb Strap for Targeted CMC Relief
- Unlike generic thumb splints, the Comfort Cool features a patented thumb strap that wraps and stabilizes the CMC joint directly, limiting the painful pinching and twisting motions that cause flare-ups — without locking your hand in place.

Thin, Breathable Construction You'll Actually Wear
- Made from ultra-thin 2mm neoprene and lined with terry cloth, this brace is soft, breathable, and discreet under gloves or sleeves. No bulk. No odor. Just relief.

Functional Support — Not Immobilization
- This is not a rigid splint. It's designed to stabilize while preserving functional grip and grasp — so you can continue working, cooking, typing, and doing what matters to you.

All-Day and All-Night Comfort
- Whether you wear it during activity or through the night to reduce morning stiffness, the Comfort Cool is built for extended use without irritation or discomfort.

Select Your Hand Orientation & Size
- This brace is available separately for right and left hands — be sure to select the correct hand orientation along with your size using our size chart to ensure a proper, supportive fit.

Comfort Cool is a trusted brand used in clinics, hospitals, and homes across the country. If you're searching for a cmc thumb brace, thumb splint, or hand brace for arthritis pain and support — this is the one professionals recommend first.
