Padded, non-elastic counterforce strap and a soft silicone ring that fits around the ulnar head. Unique soft silicone ring fits around the ulnar head to provide 360° stabilization of the distal radioulnar joint without applying painful pressure over the ulnar head. Moisture-wicking material keeps perspiration away from the skin. Fits right or left wrist. Made from: 55% Polyester; 25% Silicone; 20% Nylon. Not made with natural rubber latex.
For sizing, measure wrist circumference at the narrowest part of the wrist, next to (but not covering) the wrist bone/ulnar head.
