The Traveler's Circulation Improving Calf Sleeves

These are the calf sleeves that improve circulation in legs for more comfortable travel. The sleeves have gradient compression from 10mmHg to 30mmHg to prevent swelling and facilitate blood flow that’s typically restricted during long flights or road trips. The sleeves help reduce lactic acid build-up to soothe tight leg muscles that may become sore during long periods of immobility. The sleeve’s reinforced 76% micro-nylon/24% lycra construction allows your skin to breathe and remain comfortably dry. The thin, lightweight material allows the sleeves to be worn comfortably under pants and socks and enables complete freedom of movement. Imported. Unisex sizes are determined by the circumferences of your ankle and calf. Imported.
