GU nylon jacket? Size S. I've forgotten the product name at the time of sale, so I've listed it as a nylon jacket. It's size S, but it has a roomy fit. I think there are no noticeable stains. I don't really remember wearing it much, but it is still used, so please understand before purchasing. I apologize if I missed anything. It was folded up, so please be aware of wrinkles and fold marks. I will fold it up for shipping. Please be aware of wrinkles. No claims, no returns. Please read the profile section. Please ask if you have any questions.
