The Sigvaris 230 Cotton Series Compression Stockings come in a closed toe, calf length design that provides gradient compression to eliminate leg swelling and soreness. The stockings are available in styles to suit both men and women. There are six color choices to choose from; so, not only do the stockings match any outfit, but they provide a consistent compression therapy during wear. The Cotton Series stockings feel soft against the skin and cools skin in warm climates by allowing skin to breathe. The cotton socks are great for people with allergies or sensitive skin. Latex free. Two compression levels: 20-30 or 30-40 mmHg.
