Stretchy knee sleeve features graduated compression and far-infrared technology to help enhance circulation, ease swelling and relieve pain. Hundreds of far-infrared dotted elements surround the patella to retain body heat and massage the soft tissues around your kneecap to aid the healing process. Elastic design stretches in all directions and “knee-pocket” provides comfortable support without restricting movement. One size fits most on left or right knee. Breathable nylon/spandex. Washable. Imported.
