Vintage Champion (spark plugs) Racing Apparel fleece lined jacket large navy

Interior tag does not show where it is made or material. Metal snaps have all their paint. Waist has ties for adjustment. Wear on top of left collar. Collar is about 3.5” long so thinking jacket is 80s or early 90s. Holes and white spot on left elbow area. Champion patch on left breast. Open pockets at each side of waist. Measures about 25” pit to pit and 29” shoulder to waist. Jacket comes from Indianapolis so we think is tied to the Indianapolis 500.
