I bought this at a general goods store. I wore it twice and have stored it in the closet after washing. There are no noticeable stains, but please purchase if you understand that it is a used item. The lower half of the back is made of a stiffer, shirt-like fabric. We will take waterproof measures (compression) when shipping, so please be aware of any folding wrinkles. Feel free to comment (^^) Instant purchase is also OK!
