GU Linen Blend Long Cardigan Light gray with a stylish slub pattern Made of 49% linen and 46% rayon, this knit is a natural material. It has a smooth feel and stretches well, so I bought a size S. I tend to buy clothes made of natural materials whenever I find them because they don't generate static electricity and don't feel scratchy. It has slits at the hem, making it easy to move around in.
