Garment Measurements | Virtual Size Chart


The Iron Heart 285-OD Short Sleeve Work Shirt is a medium weight, reinforced piece produced from a 5.5 oz. sanforized and rinsed Japanese Selvedge Chambray that's appropriate as a warm weather style staple. 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. White contrast stitching is offset with a sulphur Black overdye on an indigo dyed Chambray that will soften and provide significant fading potential when worn heavily to convey that workshop class in a versatile, charcoal blue 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 dual patch front chest pockets with pencil slot, comprising a piece for the stylistically sound and self-reliant. Further, black overdyed selvedge line reveals on the placket, internal felled seams, and chainstitched construction throughout give this piece all the necessary heritage provenance, and then some. The Black Overdyed Selvedge Chambray Short Sleeve Work Shirt strikes the balance between classic and modern applications, making it a future heirloom, a seasonal go-to, and a substantial piece that will only get better with wear. Built for the biker and over-engineered to start, the Iron Heart 285-OD Work Shirt tests the limits of what actually can be artfully woven and sewn, delivering a lifetime of durability in a work-ready design.
