Vintage 1 of a Kind 1980s Sample Men’s Nike Long Sleeve Blue Pullover size Med

Based on the tag this is circa 1984-1987. It is a sample item from that time period, unknown if anything like it was ever manufactured for sale. I believe it’s a pullover sweatshirt / sweater. It’s a teal aqua blue and is in imperfect vintage condition with fading , thinning of the fabric, and pilling. I do not see stains or holes, however , making it in pretty good shape given its age. It is not a 2020’s size medium: I believe it runs small for modern men’s size Medium. Pictures show measurements. This is your chance to own a piece of Nikes history.
