This limited release of 'Wabash' Selvage Denim is a unique blend of indigo warp x black weft in a 12.5oz weight. It's this combo that produces the intensely dark face that allows for the Wabash pattern to contrast so vividly. The history of the Wabash pattern goes back further than that of denim, to the glory days of the railroad system in the United States. By the 1930's it was widely adopted as a standardized work wear pattern in most uniforms for service oriented jobs.
