Garment Measurements | Virtual Size Chart


The 235-BLK Western Shirt is a hardy, reinforced piece produced in a proprietary Japanese 13 oz. sanforized and rinsed Military Serge Twill in a solid Black color designed to evolve with its wearer. 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. This heavy duty 2x2 serge fabric provides a clean, tonally textured aesthetic with a pronounced ribbed twill weave from yarns that have been sulfur dyed to fade when worn as hard as intended. This Western has numerous and carefully considered construction and design details like the curved shoulder and triple stitched 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, internal felled seams with chainstitched construction throughout give this piece all the necessary heritage provenance, and then some. The Military Serge Twill 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 235-BLK Western tests the limits of what actually can be artfully woven and sewn, delivering a lifetime of durability in a battle-ready design.
