Iron Heart 9oz Cotton Linen Work Shirt - Black

Lightweight by Iron Heart standards, this 9oz work shirt blends the brand’s signature durability with warm-weather comfort. Made from a breathable cotton-linen fabric woven in a left-hand twill, it offers a softer feel and better airflow without sacrificing toughness.

Cut in Iron Heart’s classic work shirt silhouette, it’s triple-stitched at the major seams and reinforced with chainstitch runoff at the gussets—a build designed to go the distance. Finished with tonal hardware and utility-focused details throughout.
