The New Mountain Standard
Meet the Cast Iron Sierra Pants, built for the mountain town, the wild places, and all the spaces in-between. The Sierras combine the everyday comfort of jeans with the ruggedness of our signature Cast Iron fabric. Designed to bend, but not break with an active, 4-way stretch, the Sierras move with you—whether on a pre-dawn scramble, mid-day siesta, or late-night bonfire beers. Put on the new mountain standard, one leg at a time.
Straight through the thigh, hip and seat with a gradual taper from the knee down. View a detailed measurement chart here.
MADE FOR MOVEMENT
Built to bend and not break, The Sierras are rugged and flexible. Engineered with four way stretch for a full range of motion and reinforced with triple needle construction and heavy duty bar tacks at stress points.
CAST IRON BACKBONE
Our signature Cast Iron Fabric combines the strength of Cordura® nylon and the classic feel of cotton with the comfort of stretch. Cast Iron Fabric was developed in 2015 to provide a technical, durable and comfortable alternative to big box workwear. It has been the trusted choice of guides, growers, craftsmen and adventure enthusiasts around the world ever since.
