This is a size medium jacket, it’s more then a wind breaker, it is from the 1992 America’s Cup in San Diego, it has Hewlett-Packard on the right and the America’s cup on the left. It has the attachment where the tag was so I am assuming it has never been worn.  The brand is Pro Rainer Active Wear And has a marking of RN #77113 on the tag. All zippers work, has the main zipper and then one on each pocket.please look at all pics.
