Specifically designed to help control painful swelling of the hands. High quality, lightweight blend of 80% nylon and 20% spandex provides 23-32 mmHg of even compression throughout the hand. Seamless support at the base of the thumb and seams to the outside of the glove increase comfort and compliance. Finished edges for better quality. Gloves are easy to take on and off (because of open-cuff design), and are machine washable, air dry. Latex free.
