The 501 is not a product — it's a patent that became a uniform. Since 1873, Levi Strauss & Co.'s copper-riveted indigo work pants have dressed gold miners, cowboys, rebels, and rock stars without changing their fundamental cut.

This design system channels that permanence: deep-rinse indigo as the dominant surface, red pocket-tab accents for action, cream hangtag paper for content, and Trade Gothic's condensed ALL-CAPS authority stamped across every label. Heritage utility, not fashion.
