New: the Shiftback denim. These new Cast Iron jeans have a modern regular tapered fit that sits relaxed at the waist and tapers from the knee down. The rich, dark indigo wash gives them a premium Cast Iron denim look. The combination of the authentic denim look with the comfort of a super stretch denim makes the Shiftback stand out. In addition to the copper trimmings and the signature Cast Iron branding, new details such as the double back pocket provide the finishing touch.
