Iron Heart - IH-755-BLK - 11oz Duck Cargo Pants - Black
Couldn't load pickup availability
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, brass rivets, heavy twill cotton pocket bags, and reinforced belt loops.
This model is cut from 11oz Japanese duck, a tough plain-weave canvas that pairs naturally with the rugged aesthetic of the cargo style. As this fabric is woven with white-core cotton yarns, you can expect the black sulphur dye to gradually lighten to grey, resulting in striking high-contrast fading in areas prone to friction and wear.
