To create a new collection of old favorites, we've taken the pieces we love—from the obscure to the iconic—and evolved them into a limited-edition range of essentials we feel no guy should be without. An industrial uniform from the 1940s inspired this version in heavyweight cotton fleece. We kept the iconic workshirt detailing (metal buttons, side-entry chest pockets and a chambray-lined placket) but gave it a rich depth of color courtesy of real indigo dye. Indigo is difficult to work with, but it produces a blue like no other, so it's worth it. Please note that due to the nature of real indigo, the dye may rub off on light-colored fabric and upholstery.
