This is a thin piste. The size has faded, so I think it's 150-160. There are no noticeable stains. I bought it in a bright color to make it easier to spot my child. I'm selling it because I no longer use it. It's been stored at home and is a used item. The tag has a name written on it, but I will send it as is. Sleeve: Long sleeve Gender: Unisex
