Jobst Opaque pantyhose for men and women are smooth, soft, and breathable. A silicone finish on the yarns makes them extremely soft and easy to don. A reciprocated and reinforced heel allows for greater durability and comfort. These pantyhose provide 30-40mmHg of gradient compression and should be worn under a doctor’s supervision. This level helps relieve severe varicose veins, severe edema (swelling), and chronic venous insufficiency. Woven from a 71% nylon and 29% spandex in the USA.
