Garment Measurements | Virtual Size Chart


The Iron Heart 229-SNO Western Shirt is produced in Japan from the 12 oz. Ultra Heavy Flannel and has a double brushed interior to yield a soft hand in an extremely hardy fabric with a sophisticated black windowpane check on a winter snow white field to provide a versatile and standout palette and pattern. Made from a rare Aspero wild and organic cotton plant found only in the foothills of Northeast Peru, the yarn yields remarkable softness and an unmatched strength, treasured by the area's indigenous population for generations. Using the signature Iron Heart Western pattern, a slim fit based on the 1926 original, this shirt is perfectly proportioned in terms of length to wear untucked for modern, vintage-styled grit. This Western has numerous and carefully considered construction and design details like the curved shoulder and triple stitched back yoke, which are paired with specialty Iron Heart pearl white and nickel Permex snaps on the dual flap front chest pockets, placket, and cuffs resulting in a piece for the stylistically sound and self-reliant. Further, internal felled seams with chainstitched construction throughout give this piece all the necessary heritage provenance, and then some. The Ultra Heavy Flannel Windowpane Check Western strikes the 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 229-SNO tests the limits of what actually can be artfully woven and sewn, delivering a lifetime of durability in a roam-ready design.
