Spring/Summer ’26 introduces a new cut to the lineup — the collarless chore jacket. Like last season’s coveralls, this style is designed with a more tailored fit and flattering silhouette compared to older Iron Heart chore jackets. To achieve this, we’ve repositioned the side seams further toward the back and enhanced taper at the waist, creating a more rounded silhouette that allows for natural hand pocket placement.

Oversized for layering, key features include a secure tack button fastening placket, heavy-duty snap-fastened chest pockets, and triple-stitched seams to enhance strength. This model is cut from a unique 10.5oz Japanese herringbone twill. Initially woven from sulphur-dyed black and contrasting white yarns, the garment is then overdyed post-construction using black sulphur dye. This process dramatically reduces contrast within the weave, producing a more subtle interplay of black and grey. However, as the garment is constructed using white poly/cotton stitching — which resists dye absorption — these contrasting threads remain, highlighting the details of the cut. Additionally, as a side effect of the sulphur-based overdyeing, the metal hardware becomes oxidised and tarnished, adding to the vintage allure of this distinctive piece of workwear.
