Cotton duck is the most popular and versatile shell fabric for Carhartt outerwear. The cotton-poly blend of the QuickDuck canvas is a lightweight option. And, as the name implies, the Cordura nylon of the Extremes series is well-suited for severe conditions.

Carhartt's duck line is made from heavyweight, 12-oz., 100% cotton duck fabric that is tightly woven with no gaps where the yarns interlace—a feature that makes it wind and snag resistant. Cotton duck is known for its quality, durability and comfort. The cotton duck Carhartt uses in its outerwear has several different finishes, each with its own distinct characteristics.
