Garment Measurements | Virtual Size Chart


The Iron Heart IHSH-353-BLU Work Shirt is a hardy, reinforced piece produced from a 10 oz. sanforized Japanese Selvedge Denim made in Kojima, Japan and is Overdyed Blue to present a vibrant denim. Using the signature Iron Heart Work Shirt pattern, this piece is perfectly proportioned in length to be worn untucked for modern, vintage-styled grit. Contrast stitching is offset with a direct overdyed blue on indigo denim designed to add a brilliant hue and dramatically fade over time when worn heavily to convey an evolved workwear classic in a medium weight shirting piece that will soften to feel like a hearty chambray. This Work Shirt has numerous and carefully considered construction and design details like the squared shoulder and back yoke panel, which is paired with signature Iron Heart cats eye buttons on the front placket and dual patch front chest pockets with pencil slot, comprising a piece for the stylistically sound and self-reliant. Further, selvedge line reveals on the placket and cuffs, internal felled seams, and chainstitched construction give this piece all the necessary heritage provenance, and then some. The Indigo Overdyed Blue Selvedge Denim Work Shirt strikes the balance between classic and modern applications, making it a future heirloom, a year-round go-to, and a substantial staple piece that will only get better with wear. Built for the biker and over-engineered to start, the Iron Heart 353-BLU Work Shirt tests the limits of what actually can be artfully woven and sewn, delivering a lifetime of durability in a work-ready design.
