Comfort Cool Thumb & Wrist Splints

Comfort Cool splints are a familiar name in hand therapy, prized for their breathable, low-profile design that lets people keep working, typing, and living while supporting an injured or arthritic joint. Made from a perforated neoprene blend, these splints wick moisture and stay cooler against the skin than rigid bracing—which is exactly why hand therapists and occupational therapists reach for them for daytime, long-wear use.

This collection features the Comfort Cool CMC Restriction Splint, one of the most commonly prescribed supports for thumb basal joint (CMC) arthritis and instability. The splint restricts painful movement at the base of the thumb—the source of the aching, pinching pain many people feel when gripping keys, opening jars, or turning a doorknob—while leaving the wrist and fingertips free for everyday tasks. Because it stabilizes the CMC joint without immobilizing the whole hand, it's well suited to people who need relief but can't set aside their work or hobbies.

Fit matters with these splints, so pay attention to size and hand when ordering. The medium, right-hand version (NC79565) is sized to a specific wrist and thumb circumference, and choosing the correct side ensures the restriction strap sits properly across the joint. Hand therapists often recommend measuring per the manufacturer's chart rather than guessing, since a splint that's too loose won't control the joint and one that's too tight defeats the comfort the line is known for. Most wearers can hand-wash the neoprene and air-dry it, keeping the splint fresh for daily use.
