Garment Measurements | Virtual Size Chart


The Iron Heart IHSH-285-PIN Short Sleeved Work Shirt is a medium weight, reinforced piece produced from a 5.5 oz. sanforized and rinsed Japanese Selvedge Pinstripe Chambray that's appropriate as a warm weather style staple. 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 indigo dyed warp and weft with a woven pinstripe to create a vintage-inspired blue and white palette that will soften and wear-in with subtle fading to convey workshop class. 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, red selvedge line reveals on the placket and side seam gusset combined with internal felled seams and chainstitched construction with inseam run-off give this piece all the necessary heritage provenance, and then some. The Indigo Pinstripe Selvedge Chambray Short Sleeved 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-PIN Work Shirt tests the limits of what actually can be artfully woven and sewn, delivering a lifetime of durability in a work-ready design.
