The 3pp ThumSling is a soft, lightweight splint that applies light compression to relieve arthritis pain at the base or CMC joint of the thumb. The ThumSling gently holds the joint without limiting motion or function. Features The wrap-around sling adjusts to your level of comfortable support. Designed to hold the CMC joint in the proper position so you can perform daily activities with less pain or fear of dropping things due to CMC arthritis. The non-bulky, soft splint allows gripping a golf club, holding a rake or gripping a pen securely and comfortably. Foam-lined material contours to the hand for a non-bulky support that can be worn all day or night. Easily increase the level of support by adding the flexible stay (included) for additional control wherever it's needed. Hand or machine washable. Latex free.
