Vintage Blue Bomber Jacket Union

Vintage Blue and Yellow Union bomber jacket. No size marking but I have measurements in the pictures. Not sure what the fabric is but I think it’s Polyester. It is Pre Owned it is vintage and there is some small holes at the bottom inside of the jacket and one large spot where the lining on the inside has separated from the polyester as well as another small hole again all on the inside. Also some small stains near the end of the sleeves and one or two other spots but those are barely noticeable at all.
