226-IYE - Work Shirt - 5.5oz Selvedge Madras Check Indigo & Yellow


Garment Measurements | Virtual Size Chart


The 226 Work Shirt is a medium weight, reinforced piece produced from a 5.5 oz. sanforized and rinsed Japanese Selvedge Madras box-weave fabric that's appropriate for warm weather yet substantial enough for year-round use. Using a perfect palette of indigo dyed yarns for the blues that combine with a sulphur dyed yellow over an off-white field, this heavy duty oxford style cloth is designed to evolve, conveying workshop class through fading and patina potential. Coming 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 yoke, which is paired with signature Iron Heart white 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, selvedge line reveals, internal felled seams, and chainstitched construction with inseam run-off give this piece all the necessary heritage provenance, and then some. The Selvedge Madras 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 226 tests the limits of what actually can be artfully woven and sewn, delivering a lifetime of durability in a work-ready design.
