Woolrich vintage Aztec jacket

The wool Astec pattern part of the jacket is removable so then it just turns into a regular teal jacket. The jacket is heavy duty and is very durable. My mother gave it to me, but it is not my style, and it no longer fits her so we both decided to sell it. There is a small stain on the back that is barely noticeable. I noticed it only when I went to take the photo.
