Iron Heart | IHJ-148-BRN | 10oz Kurashikizome® Organic Cotton Duck Chore Jacket | Brown

Fall/Winter ’25 introduces a new chore jacket cut to the lineup, blending practicality with contemporary style. This season’s models feature a more versatile pocket layout than previous Iron Heart coveralls, and a slimmer, more flattering silhouette. Key features of this updated cut include flapless chest pockets complete with a pen holder (inspired by the IH signature work shirts) and large flap-down waist pockets that double as side-entry handwarmers. Each pocket is secured with oversized snap fastenings for quick access, while the main placket uses heavy-duty tack buttons for strength. 


This model is cut from 10oz organic cotton duck canvas, creating a lightweight but highly durable chore coat. Environmentally friendly and sustainably sourced, the 100% organic cotton is farmed without synthetic pesticides or fertilisers, resulting in longer, stronger fibres. Once spun into yarns, the cotton is then dyed under the eco-friendly Japanese Kurashikizome® certification. This dyeing process is free from harmful chemicals and uses minimal resources, with all wastewater thoroughly purified before being returned to the ocean. The result? A long-lasting workwear fabric that meets the needs of the environmentally conscious wearer.
