Garment Measurements | Virtual Size Chart


The Iron Heart IHSH-369-GRY Western is produced in Japan from a 12 oz. Slubby Heavy Flannel and has a heavily textured unbrushed exterior for a rustic finish and double brushed interior to yield a soft hand on body in a hardy fabric. A classic check in off-white, black, and pumpkin on a grey field with a unique herringbone weave provides an updated and versatile palette in a traditional workwear pattern. For a new take on an icon, this is the first time a slub yarn has been used in the classic Ultra Heavy Flannel weight to give flexibility and a textured and worn appearance in a dutiful and substantial fabric. Using 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 that 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, internal felled seams and chainstitched construction give this piece all the necessary heritage provenance and then some. The Slubby Heavy Flannel Herringbone Check Western strikes a balance between classic and modern applications, making it a future heirloom with endless fall through spring applications. Built for the biker and over-engineered to start, the Iron Heart 369-GRY once again tests the limits of what can be artfully woven and sewn, delivering a lifetime of durability in a road-ready design.
