The Iron Heart IHSH-349-GRN 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. 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 Work Shirt pattern, this piece is perfectly proportioned in 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 and back yoke panel, 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 red thread chainstitched construction with 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 349-GRN tests the limits of what actually can be artfully woven and sewn, delivering a lifetime of durability in a workshop-to-street ready design.
