In response to popular demand, Sigvaris now offers its sports performance sleeves in red. Sigvaris performance sleeves help improve circulation and flush out lactic acid after a workout. The sleeves are measured at the ankle and calf for an accurate fit and provide 20 to 30 mm Hg of medical-grade graduated compression. The graduated compression in Sigvaris performance sleeves helps fight the force of gravity and circulate blood to the heart and lungs more efficiently, thus helping to improve athletic performance. The sleeve is made from a comfortable, fast-drying fabric that may be worn on land or in water.
