The Featherweight Compression Leg Sleeves are made of an ultra-thin material that is breathable and moisture wicking. The Featherweight Leg Sleeves offer a more compressive fit than our original compression leg sleeves (item #6055). Graduated compression helps to improve circulation, reducing muscle recovery time. It also helps to relieve shin splints and prevent calf cramping. The leg sleeves feature a special anatomical fit for optimal fit and performance. Use the leg sleeves for everything from running to basketball.
