In like new condition Originally released as the "501® Z," these 1954 501® jeans represent our expansion into new territory. Up to this point, Levi's® denim was primarily worn out West, where it had earned a loyal following. East Coasters, however, were largely unfamiliar with this button-fly work pant. In order to familiarize the East Coast with this American classic, we took the original 501® Shrink-to-Fit™ jeans and replaced the classic button fly with a zipper, and named it the "501® Z." It retained all the other details loved by longtime wearers: the famed silhouette, rivets and tough-but-flexible denim. Eventually, retailers began providing customers with both options—the 501® jeans and its zippered brother, the 501® Z. Today, we recreated the latter in classic selvedge denim. These 1954 Men's 501® jeans help tell the story of the 501® and its evolution through the decades.
