Jobst Opaque pantyhose for men or women are smooth, soft, and breathable. A silicone finish is used on the yarns which makes them extremely smooth and easy to don. A reciprocated and reinforced heel allows for greater durability and comfort. These pantyhose provide 20-30mmHg of gradient compression and help improve blood flow, prevent edema (swelling), and reduce the discomfort caused by moderate to severe varicose veins. Woven from a 73% nylon and 27% spandex in the USA.
