Cast Irons have been trusted by everyone from guides and growers, to brewers and builders for nearly a decade. Constructed with our signature Cast Iron Canvas that combines the natural feel and classic look of cotton with the strength of Cordura® Nylon. Cast Iron Canvas is 3X more durable than traditional cotton workwear fabric. Built with a comfortable contoured waistband, a streamlined fit, and an action gusset for increased range of motion where it counts, every detail of our Cast Iron Utility Pants is carefully considered — right down to the very last stitch.
