Made of sturdy, firm nylon fabric, I think it will keep out rain and wind. The tag says it's a free size. Measurements taken by a layman: shoulder width 43cm, body width 55cm, length 72.5cm, sleeve length 65cm. It's reversible, with gray and glossy black sides. There's a small stain on the collar of the gray side, so I've marked it as "slightly damaged or dirty," but overall, I think it's in relatively good condition. (See photo 6) Two spare buttons are included.
