Levi's Blue Tab is an elevated collection that infuses our iconic denim heritage with traditional craftsmanship. Expect thoughtful details, sharp tailoring and finishes that are rich with character. This is an entirely new shape of Blue. The original zip fly. First created in 1967, our 505 jeans are one of our most popular straight fits. Beloved for their classic style, they're cut to sit at the waist with extra room in the thigh.
