This is a Call & Response camouflage nylon blouson. It has been worn about 10 times and is still in good condition with no noticeable stains or damage. I think you can still wear it comfortably. There are no smokers in my family, so please rest assured. I don't sit on the street or in unsanitary places, and I mostly travel by car, so it's clean. I couldn't find a size tag. I think it's probably equivalent to M-L. Shoulder width: Approximately 47cm Width under the armpits: Approximately 53cm Length: Approximately 63cm Sleeve length: Approximately 61.5cm
