This is a reverse weave with ribbed lines, featuring an embroidered chest. The front embroidery, with the U.S.A. notation and a sailboat motif, is believed to have been added later for use by a U.S. Navy (Navy) related club or for recreational purposes. It's likely from a yachting/sailing club or event, rather than a combat unit insignia. Although not an original Champion specification, it's a one-of-a-kind item with a great atmosphere and story, likely customized in the 80s-90s.
