Which American brand introduced the 13MWZ cowboy cut in 1947?

Wrangler introduced the 13MWZ Cowboy Cut in 1947.

The 13MWZ became Wrangler’s signature cowboy jean. Its design was developed for rodeo riders and working cowboys, with a fit intended to work comfortably with boots and riding gear. The model’s name is commonly expanded as “13-ounce, Men’s Western Zipper,” referring to its fabric weight, target wearer, and zipper fly.

Wrangler worked with rodeo professionals, including tailor and rodeo champion Bernard Lichtenstein, known as Rodeo Ben, during the development of its western jeans. That practical testing helped the brand distinguish the Cowboy Cut from ordinary work trousers.

The 13MWZ is sometimes confused with Wrangler’s introduction year or with later numbered fits. The brand debuted in 1947, and the 13MWZ is the specific classic cowboy-cut model associated with that launch period.
