Garment Measurements | Virtual Size Chart


The 33-BLK Western Shirt is a hardy, reinforced piece produced from a 12 oz. sanforized and rinsed Selvedge denim from Kojima, Japan. Using the signature Iron Heart Western pattern of a slim fit based on the 1926 original, this shirt is perfectly proportioned in terms of length to be worn untucked for modern-vintage styled grit. Contrast dark gold and brown stitching combined with a black sulphur dyed warp and natural weft selvedge denim convey a rugged aesthetic that deepens over time. When matched with hard working sensibilities, this piece will yield a worn grey fade that will evolve with each wash. This Western has numerous and carefully considered construction and design details like a curved shoulder and triple stitched back yoke panels, paired with signature Iron Heart black Permex snaps on dual flap front chest pockets, placket, and cuffs to make a piece for the stylistically solid and self-reliant. Further, selvedge line reveals, internal felled seams, and chainstitched construction with inseam run-off give this piece all the necessary heritage provenance, and then some. The Black Selvedge Denim Western strikes the balance between classic and modern applications, making it a future heirloom, a year-round go-to, and a new project piece that will become unique to its wearer. Built for the biker and over-engineered to start, the Iron Heart Western tests the limits of what actually can be artfully woven and sewn, delivering a lifetime of durability in a range-ready design.
