What does Unwashed mean?
As the name implies, denim that has been unwashed and untreated. To some, it is considered to be “old-fashioned” since manufacturers originally sold their garments dark, stiff and not pre-shrunk.

Unwashed denim is also known as rigid, or, in our case, raw denim. Unwashed jeans are stiff and dark in color, and it is up to the consumer to break the jeans in, simultaneously customizing the pants to his/her own body. See raw denim for more information.
