NuVein is available in "Medium Strength" compression. Compression strength is measured in "mmHg" pressure, which indicates how tight the garment will feel. Choose 10-20 mmHg (medium strength) compression to revitalize legs with discomfort, swelling, bulging, or blood clots (fluid buildup post surgery). Travelers who experience "economy class syndrome" or "jet leg" should wear 10-20 mmHg, as should pregnant, expecting or nursing mothers. Commonly used as the starting point for everyday wear, travel, leg health, prolonged sitting or standing, increased blood flow, energy, and recovery from intense training or workout on muscles. Designer compression that heals while it conceals.  Always confirm the correct compression strength prior to purchase. Integrated compression technology promotes recovery, circulation, and healthy legs. Ideal for nurses, those experiencing spider veins or varicose veins, active use for light jogging, walking, running, and those expecting long flights or extended periods of inactivity.
