The compressive effect is based on medical standards i.e. it decreases from knee to thigh promoting circulation. The muscles receive a better supply of oxygen continue to perform more effectively and regenerate faster. Stimulating blood circulation also causes the thigh muscles to quickly heat up which makes them better protected. The compression reduces uncomfortable muscle vibrations thus preventing premature fatigue. The sleeves which come in a sporty design are available as a pair and are durable breathable and fit securely thanks to a silicone top band on the upper edging.
