Weatherproof Vintage Cardigan - Men's Size M

Weatherproof Vintage Cardigan - Men's Size M Navy blue and gray pattern cardigan by Weatherproof Vintage. Sweater is missing the fourth (top) button; although I'm not sure if this is a flaw or if it's by design because there doesn't appear to be any remnants of stitching in the place of where the missing button would go. Pre-owned; clean and very good condition. Care instruction tags have been cut off (see last photo).
