Our classic work shirt cut, constructed from a 9oz cotton/linen fabric. Woven with a traditional left-hand twill, the 90% cotton / 10% linen blend creates a softer, more breathable cloth while maintaining the rugged characteristics expected of an Iron Heart fabric. This results in a hardwearing yet comfortable shirt that provides excellent ventilation throughout the warmer seasons. With features including button fastenings, a chest pocket pen holder, and side seam gussets with chain stitch runoff, this model bears all the hallmarks of our work shirt cut—with additional triple-stitched side, arm and shoulder seams for enhanced durability.
