Silkier and softer to the touch than pure cotton, these Charnos Cotton Modal Socks feel great against the skin. Although cotton is a great fibre, blending it with modal makes it perform so much better too. Modal (sometimes called rayon) prevents shrinkage, increases absorbency and improves wicking. These ladies Charnos Cotton Modal Socks are lightweight and fine woven. They come as a twin pack of matching colours and are in an ankle length suitable for all uses.
