The SIGVARIS Cotton 230 collection is designed to ensure correct fit and accurate compression, resulting in optimum therapeutic benefits and greater wearing comfort. The socks and thigh-highs are constructed with 25 percent Supima® Cotton for all-day comfort, breathability and durability. The product is ideal for those with sensitive skin and allergies, as only cotton touches the skin. The Cotton Series is often recommended by physicians for patients with venous disorders or as treatment after a Deep Vein Thrombosis (DVT).
