This item was given to me, and I haven't used it. The tags have been cut off, so I don't know the size or material. I think it's a size S. It's very light, and the inside is mesh, so I think it's a summer material. It doesn't appear to have any noticeable stains, but it's a used item, so please understand. I will fold it compactly for shipping. Please be aware of this. No comments needed, instant purchase is OK.
