Vintage Yale University Swim Team #13 1960's / 1970's Official Warmup Jacket.
Made by U.S. Swimwear, Inc., Irvine CA. Size: Large 100% nylon exterior, fleece-lined interior.
Issues: the zipper is not working, there are two small snag holes near left pocket, fraying along left front hood, fraying along rear bottom.
One of a kind piece of functional Yale memorabilia that I believe to be as early as 1960's and as late as mid-1970’s. Can easily be restored. I've searched far and wide and have not seen another ever sold.
