I bought this a few years ago and have only worn it a few times. I don't think there are any noticeable stains, but as you can see in the photos, there's a small red stain? and a stain like a ballpoint pen on the bag. I'd like to sell it to someone who doesn't mind. It fastens with Velcro, so it's easy to put on(^^) It comes with a dedicated bag that's convenient for carrying. *There are some stains on the bag. See the photos. I think the size is around 80-90.
