Henry David Lee set up the HD Lee Mercantile Co in Kansas, 1889 specialising in the production of denim dungarees, overalls and railroad jackets. In 1924 Lee released the 101B Cowboy jeans, the first denim trouser specifically designed for cowboys and rodeo riders, followed by the 101Z in 1926, the first ever zip-fly jeans. In 1944 they re-branded the cowboy range as Lee Riders and introduced the famous Lazy-S stitching on the back pockets. Years later and Lee are still top dogs in the denim world.
