Garment Measurements | Virtual Size Chart


The Iron Heart IHSH-266-IND Work Shirt is a hardy, reinforced piece produced in a 12 oz. medium weight, sanforized, and once-washed right-hand twill from Kojima, Japan, designed to evolve with its wearer. Using the signature Iron Heart Work Shirt pattern, this piece is perfectly proportioned in length to be worn untucked for modern, vintage-styled grit. A cult collectible fabric within the Iron Heart collection, this 100% Cotton twill is woven using indigo rope-dyed yarns for the warp and weft. It is block printed with a technique using bleach to create the dotted stripe Wabash pattern, which is synonymous with railroad workwear garments of the early 20th century. This fabric has a structured form that will evolve into a natural drape and develop remarkable fade patterns when worn as hard as intended. This Work Shirt has numerous and carefully considered construction and design details like the 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 a pencil slot, comprising a piece for the stylistically sound and self-reliant. Further, white stitching and red thread for bartacks, internal felled seams, and chainstitched construction throughout with inseam run-off give this piece all the necessary heritage provenance and then some. The Wabash Twill Work Shirt balances classic and modern applications, making it a future heirloom, a year-round go-to, and a new project piece that will only improve with wear. Built for the biker and over-engineered to start, the Iron Heart 266-IND Work Shirt tests the limits of what can be artfully woven and sewn, delivering a lifetime of durability in a work-ready design.
