Description
The Iron Heart IHSH-21-BLU Work Shirt is a medium weight, reinforced piece produced from a 10 oz. sanforized and rinsed Japanese Selvedge Chambray that's appropriate as a style staple for year-round use. Using the signature Iron Heart Work Shirt pattern, this piece is perfectly proportioned in length to be worn untucked for modern, vintage-styled grit. White contrast stitching combines with the blue reactive dyed warp and weft to create a textured, bright blue Chambray that will soften and wear-in without any significant fading to convey workshop class in a versatile and consistent vintage-inspired palette. This Work Shirt has numerous and carefully considered construction and design details like the triple stitched squared shoulder and back yoke panel, which is paired with signature Iron Heart cats eye buttons on the front placket and dual patch front chest pockets with pencil slot, comprising a piece for the stylistically sound and self-reliant. Further, selvedge line reveals on the placket and cuffs, internal felled seams, and chainstitched construction with inseam run-off give this piece all the necessary heritage provenance, and then some. The Blue Selvedge Chambray Work Shirt strikes the balance between classic and modern applications, making it a future heirloom, a year-round go-to, and a substantial staple piece that will only get better with wear. Built for the biker and over-engineered to start, the Iron Heart 21-BLU Work Shirt tests the limits of what actually can be artfully woven and sewn, delivering a lifetime of durability in a work-ready design.

Iron Heart Shirting sizing is graded in small increments. The 21-BLU runs true to Iron Heart sizing. This piece is made with a sanforized fabric and has been once washed to remove most shrinkage. With regular use, one can expect up to .5” of stretch in the chest (Circumference) over the long term.
Our Method of measuring is different than Iron Heart’s and we recommend consulting our Sizing Guide when purchasing. We provide garment-specific measurements taken in-house, per Our Method, that are not duplicated across fabric or colorways and are re-measured each production run.
