I've used this about three times since I bought it, and then stored it after washing. It's a bit too big for me, so I stopped using it. I think it's hard to find now. It's been so hot lately, so how about using this to prevent heatstroke? As you can see in the photos, there's some staining on the inside that didn't come out after washing. It's on the inside, so it's not very noticeable.
