The Thermoskin Cross-X CMC Thumb Splint offers superior support and compression of the CMC joint. The anatomical glove design allows for easy application and maximum comfort while the exclusive Cross-X power point thumb loop provides increased stability to the critical CMC joint. This patented and fully adjustable Cross-X thumb loop crosses over itself to create an "X" and provide maximum control of the CMC joint while allowing for full function of the wrist and hand. The Cross-X CMC Thumb Splint helps relieves thumb pain and inflammation associated with joint arthritis, instability, tendonitis and repetitive stress injuries. Thermoskin Thermal Supports utilize the exclusive patented Trioxon® lining that is clinically proven to capture your natural body heat. Unlike other products, Trioxon allows your skin to ventilate and remain comfortably dry even with long-term use. Competitive products trap the perspiration resulting in discomfort, slippage, risk of infection and unpleasant odor. The Trioxon lining creates a microclimate to help the skin breathe while still providing effective heat therapy. This is the secret of Thermoskin"s long-term comfort for the user. You can even wear Thermoskin for extended periods of time without the discomfort you would have with other products. How Thermoskin works: The application of prolonged heat therapy to the effected area is a simple and quick form of treatment. Heat therapy promotes healing by opening up the small blood vessels, increasing blood flow and facilitating the removal of inflammation. Heat therapy assists your body"s natural healing process. The combination of this heat therapy along with the support and light compression provided by Thermoskin Thermal Supports help prevent, treat and rehabilitate soft tissue injuries.
