This is a child's sleep sack. It's a sleep sack with an elephant pattern, purchased from Akachan Honpo. There is no size label, but I think it's around size 80-90. Length is about 63cm. The back is mesh, so it's breathable. I wore it for one season. There are no stains, but there are some pills on the pile and the fabric on the back. Please check the photos for confirmation.
