Comfort Cool Thumb CMC Restriction Splint, Neoprene Thumb Brace

Keep using your hand while the Comfort Cool Thumb CMC Restriction Splint supports your thumb

The Comfort Cool Thumb CMC Restriction Splint is a soft, flexible thumb brace that supports the CMC joint at the base of your thumb while leaving the rest of your hand free to work. It is made to be worn through the day during normal activity, and it is listed for CMC joint arthritis and instability, tendonitis, tenosynovitis and repetitive strain injuries.

Why You'll Love the Comfort Cool Thumb CMC Restriction Splint

1. Support right where it aches. A padded, contoured thumb strap wraps around the base of the thumb to give compression and joint support.
2. Your hand still works. It limits thumb movement just enough while still letting you grip and pinch between thumb and forefinger, so writing and everyday jobs carry on.
3. Cool and comfortable all day. Perforated 1.57mm neoprene with a terry cloth liner helps keep your skin cool, and minimal edge stitching means a softer feel on the skin.
4. A fit that's yours. Hook and loop straps adjust quickly, and reinforced stitching lets it be trimmed below the thumb MP joint for a custom fit.

Life with the Comfort Cool Thumb CMC Restriction Splint

Think about the small things that make a sore thumb so noticeable: turning a key, opening a jar, holding a pen. With the splint on, the base of your thumb has steady support while your fingers keep doing their job. It slides on and off without help, so you can pop it on in the morning and get on with your day.

The Comfort Cool Thumb CMC Restriction Splint in a nutshell

1. Latex-free neoprene: perforated 1.57mm (1/16") neoprene supports the CMC joint and suits people who need to avoid latex.
2. Terry cloth liner: a soft lining that helps keep your skin cool and comfortable.
3. Trimmable design: reinforced stitching allows trimming below the thumb MP joint.
4. Six sizes, left or right: Small to Large+ in left and right hand versions, sized by MCP circumference.

Choosing the right size and side

Sizing is by the MCP circumference: the distance around the hand at the big knuckles. Measure the hand the brace is for, relaxed, with the tape snug but not tight.

1. Measure around the knuckles. Wrap the tape around the hand at the big knuckles and note the measurement in cm.
2. Pick the size from the table below.
3. Enlarged thumb? Comfort Cool Plus sizes are half a size bigger in the hand and a full size bigger around the thumb. If the base of the thumb is enlarged, the Plus size in your range may fit better.
4. Between sizes? Some ranges overlap. If your measurement fits two sizes, email us and we'll help you choose.
5. Choose the side. Order Left for the left hand and Right for the right hand.

Is it the right thumb brace for you?

• A good fit: day-long wear during normal activity, where you want the base of the thumb supported but still need to grip, pinch and write.
• Check with your therapist first: if the thumb sits in against the palm. The Comfort Cool Thumb CMC Abduction Splint is made for that.
• Good to know: it's latex-free neoprene with a terry cloth liner, and it can be trimmed below the thumb MP joint for a custom fit.

Every hand and every recovery is different, so we recommend speaking with your healthcare provider or hand therapist about whether this is the right option for you.
