Garment Measurements | Virtual Size Chart


The Iron Heart IHSH-318-BLK Western Shirt is a medium weight, reinforced piece produced from a once washed 6 oz. Japanese Selvedge Unbrushed Flannel that's appropriate for year-round use and features a sophisticated Viyella gold, charcoal, and grey check on a black field to provide an updated, versatile palette to a traditional countryside pattern. Using sulfur dyed yarns in a directional twill weave that's made for hard duty, this flannel with a classic palette is designed to evolve and convey that ranch-ready status through fading and patina potential. Coming in the signature Iron Heart Western pattern of a slim fit based on the 1926 original, this shirt is perfectly proportioned in length to be worn untucked for modern-vintage styled grit. This Western has numerous and carefully considered construction and design details like the triple stitched curved shoulder and 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 on the placket and cuffs, internal felled seams, and chainstitched construction with a gold thread interior give this piece all the necessary heritage provenance, and then some. The Black Viyella Check Selvedge Flannel 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 318-BLK tests the limits of what actually can be artfully woven and sewn, delivering a lifetime of durability in a range-ready design.
