Garment Measurements | Virtual Size Chart


The Iron Heart IHSH-348-GRN Western is a heavyweight, reinforced piece produced from a once-washed 9 oz. Japanese Selvedge Unbrushed Flannel that's appropriate for year-round use. A sophisticated green ombre check on a deep indigo field serves as an updated and versatile pattern in a traditional workwear palette. Using extremely dark rope dyed indigo yarns that read almost black, which are accented with sulfur dyed shades of green designed to evolve, this shirt will convey workshop class through fading and patina potential. Leveraging 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, which are paired with signature Iron Heart black Permex snaps on the dual flap front chest pockets, placket, and cuffs to make a piece for the stylistically sound and self-reliant. Further, red selvedge line reveals, internal felled seams, and red thread chainstitched construction give this piece all the necessary heritage provenance, and then some. The Selvedge Flannel Ombre Check 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 only get better with wear. Built for the biker and over-engineered to start, the Iron Heart 348-GRN tests the limits of what actually can be artfully woven and sewn, delivering a lifetime of durability in a road-to-street-ready design.
