3pp ThumSling NP is designed to relieve pain from CMC joint arthritis or instability with adjustable compression and moderate support. The ThumSling NP has a contoured strap that supports the thumb and wrist to control motion and relieve pain at the base of the thumb. Features The dense foam of the 3pp ThumSling NP offers the next level of support and control for those who need more control to reduce. Like the original ThumSling, the ThumSling NP is fully adjustable so the wearer determines how much compression to apply to stabilize the thumb and relieve pain during activity and at rest. Resilient, breathable material has light stretch that contours to the hand without being bulky or restrictive. The flexible stay (included) can be added wherever extra support is needed to control motion. Hand or machine washable. Latex-free.
