Garment Measurements | Virtual Size Chart


The Iron Heart IHSH-395-BLK Work Shirt is a lightweight, reinforced piece produced from a sanforized and rinsed 7 oz. Japanese Fatigue Cloth for a warm weather style staple appropriate 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. This 100% Cotton poplin cloth was developed to evolve original battledress uniform fabrics from the 40s and 50s and was used to combat warmer temps with trademark durability. This garage-inspired Black piece is woven from consistent reactive-dyed yarns, combined with tonal stitching to produce a clean palette staple that will maintain its finish through years of hard use. This Work Shirt has numerous and carefully considered construction and design details like the squared shoulder and back yoke panel, which is paired with black concave military-grade melamine 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, internal felled seams and chainstitched construction with inseam run-off give this piece all the necessary heritage provenance and then some. The Black Fatigue Work Shirt balances classic and modern applications, making it a future heirloom, a year-round go-to, and a substantial staple piece that will only improve with wear. Built for the biker and over-engineered to start, the Iron Heart 395-BLK Work Shirt tests the limits of what can be artfully woven and sewn, delivering a lifetime of durability in a work-ready design.
