100% Cotton MADE IN USA Equivalent to Japanese XL This is a plain long-sleeve t-shirt that American Apparel produced for Supreme. American Apparel went bankrupt in 2017, and these t-shirts were found remaining in their warehouse. They were abundant in the market until a few years ago, but their circulation has been decreasing recently. There is a watermark of SUPREME on the back of the tag. The watermark proves its authenticity. Please be assured that this is not a counterfeit.
