I received this new, and I haven't used it either. There's a little bit of dirt on the green part, but it hasn't been used. The inside is boa-lined, so I think it will be warm. It can be attached anywhere with Velcro, and the size can be adjusted, so I think it can be used for a long time ^_^ It's a shame to throw it away, so I hope someone will use it. ♪
