Garment Measurements | Virtual Size Chart


The 277-IND Work Shirt is a heavyweight, reinforced piece produced from a once washed 9 oz. Japanese Selvedge Unbrushed Flannel that's appropriate for year-round use with a sophisticated indigo-to-blue ombre check on a navy field to provide an updated and versatile pattern in a traditional workwear palette. Using extremely dark rope dyed indigo yarns that read almost black that are accented with sulfur dyed shades of blue for a classic palette designed to evolve, this shirt will convey that workshop class through fading and patina potential. Using the signature Iron Heart Work Shirt pattern, this piece is perfectly proportioned in terms of length to be worn untucked for modern-vintage styled grit. This Work Shirt has numerous and carefully considered construction and design details like the squared shoulder placket, which is paired with signature Iron Heart vintage black cats eye buttons on the dual patch front chest pockets with pencil slot, placket, and cuffs to make a piece for the stylistically sound and self-reliant. Further, red selvedge line reveals, internal felled seams, and chainstitched construction with red thread inseam run-off give this piece all the necessary heritage provenance, and then some. The Selvedge Flannel Ombre Check Work Shirt 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 277-IND tests the limits of what actually can be artfully woven and sewn, delivering a lifetime of durability in a shop-to-street ready design.
