I purchased this from a GU store about two years ago. Product number: 261-349571 (41-01) I only tried it on indoors. I have not worn it outside. I am selling it because I haven't had a chance to use it. There are no stains. I have checked it carefully, but there may be minor oversights. Please purchase only if you understand that this is a used item. There are no smokers in my household. I do not have any pets. I do not accept price reductions, complaints, or returns. Color: Black系 (Black-based) Stains, tears, odors, etc.: None
