Description
The Iron Heart IHSH-442-ORA Work Shirt is a heavyweight, reinforced piece in a once-washed, Orange 9 oz. Japanese Selvedge Unbrushed Flannel, suitable for year-round use. A classic check in sage, black, off-white, and gold on a dusty sunset orange field updates a versatile retro palette with a traditional workwear pattern. Utilizing 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 features numerous carefully considered construction and design details, such as the squared shoulder and back yoke panel, complemented by white, concave, military-grade melamine buttons on the front placket and dual patch front chest pockets, placket, and cuffs, making it a piece for the stylistically sound and self-reliant. Additionally, the red selvedge line reveals on the placket and cuffs, internal felled seams, and orange thread chainstitched construction with inseam run-off give this piece all the necessary heritage provenance and then some. The Selvedge Flannel Orange Check Work Shirt balances classic and modern applications, making it a future heirloom and a year-round go-to that will only improve with wear. Built for the biker and over-engineered from the start, the Iron Heart 442-ORA tests the limits of what can be artfully woven and sewn, delivering a lifetime of durability in a workshop-to-road-ready design.
