This is a nylon jacket, a collaboration between Adidas and BEAMS. The stripes have different colors on the left and right sides, white and black respectively. I bought it in the women's section of a BEAMS store, but the size feels like it could be unisex. I've worn it a few times, but I don't think there are any stains. It's thin and very easy to wear. I will fold it up small for shipping.
