Please read my profile. Shoulder width 44cm, body width 54cm. Size and material are unknown. Looks like wool. I'm 170cm tall and slender, and it feels a bit tight with a sweatshirt on. It feels like a slightly small M size. There are some stains on the exterior, some fraying on the ribbing, and a tear in the lining of the collar. It's a reasonably clean used item at a glance.
