IH-734-BRN - 17oz Duck Cargo Pants - Brown

$ 424.00

The Iron Heart 17oz Duck Canvas Cargo Pants embody the brand’s workwear DNA at its toughest. Cut from dense Japanese duck canvas, these cargos carry the unmistakable texture and durability of traditional military gear - made heavier and stronger through triple-needle construction, double-layered knees, and reinforced rivets throughout. The 17oz duck cloth strikes that ideal middle ground between structure and flexibility, softening with wear while maintaining its rugged shape. The heavy twill pocket bags and seven reinforced belt loops highlight Iron Heart’s obsession with overbuilding even the smallest details.

The fit is traditionally relaxed, designed for mobility and durability rather than taper or trimness, making them a genuine reproduction of battle-ready field trousers. Brown warp and weft threads bring a uniform tone that will evolve slowly through wear and washing, developing a depth of character unique to each wearer. True to Iron Heart form, these cargos are built for decades of hard use, from workshop to weekend.

Fit Notes: Shop owner Tommy is wearing a size 35 in these. He has decided to size up even once more to get the fit he wants in the leg. While the waist is a little roomier than most would want, it's what he prefers to get his best fit in the leg. We would recommend sizing up at least once in these if you don't know your size. Tommy is 5'10", 162lbs with a 33-34" true waist.
