The tension can be easily adjusted for patients with disproportionate forearm and wrist circumferences. Soft proprietary felt liner contains polypropylene and wicks moisture away from the skin. The outer perforated suede laminated to the felt maintains breathability and strengthens support. Memory foam padding in palm and around base of thumb enhances comfort and support. The dorsal, palmar and radial aluminum stays are removable to allow bending by a medical professional to create a custom fit
