The indigo leaf designed with paint and stitch, bar tacking using green thread, and a gauze patch illustrates the Billiken. This design reflects what BROWN-DUCK&DIGGER is about. Our basic lineup of 1900's, 1910's, 1950's, 1960's historical series are available. In addition, all series are equipped with the ultra durable continuous fly which is made of one front piece placed from left to right that extends beyond the sturdiness of crotch rivet. This method represents an example of how we make the very best jeans.
