Men’s Volcom vest in gray cotton and 100% satin lining and back. Worn by my husband in college more than 10 years ago. Yes, those could be his sweat stains on the back of the vest or possibly beer stains. It has been washed when it should have been dry cleaned 🙈 So this is why the stains never came out. According to many Google searches the stains can come out with a light home made vinegar and lemon juice solution. Think of it as a fun project piece! Selling this vest as is! This item comes from a smoke-free/doodle loving home!🐕✨
