Actual Measurements: Length 52cm, Shoulder Width 33cm, Chest Width 33cm, Sleeve Length 26cm The fabric is a mix of dark gray and white fibers. The collar has some height and a gathered look, rather than being a turtleneck that you fold over. It keeps your neck warm, and although it's short-sleeved, it's a winter material, so it's suitable for layering with knitwear or as an inner layer under outerwear.
