17oz Duck Cargo Pants IH-743-BRN - Brown

The Iron Heart IH-743-BRN Duck Cargo Pants are available at Rugged Gentlemen Shoppe with fast local shipping and easy returns. Iron Heart produces many garments in limited runs, and certain sizes can become difficult to find once they sell through across retailers. If your size is currently available here, it can be secured while stock lasts.

Our classic cargo pants, cut from 17oz Japanese duck canvas. Designed for a traditionally relaxed fit, our cargo pants exemplify the military-grade engineering that has become synonymous with Iron Heart — with features including triple-needle stitched seams, double-layer knees, brass rivets, heavy twill cotton pocket bags and reinforced belt loops.

Our Fit Notes

The IH-743 cargo pants are cut with a traditional relaxed workwear fit, offering comfortable room through the thigh and leg. The silhouette prioritizes durability and mobility rather than a slim modern profile, staying true to classic military and utility pant designs.

Our Fabric Notes

These pants are made from 17oz Japanese duck canvas, a dense and durable cotton fabric often used in traditional workwear. The plain-weave construction gives the fabric a firm structure, while the brown dye will gradually develop character with wear and washing.

Who This Is For

Well suited for those who prefer a functional workwear fit with extra room for comfort and movement. Ideal for those looking for a tough workwear fabric with substantial weight and long-term durability.
