20oz Paraffin Coated Duck Chore Jacket - Black

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 our 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 not for the faint-hearted, as it’s cut from heavyweight 20oz paraffin-coated Japanese duck canvas. If you’re familiar with our popular 17oz duck, you’ll know exactly what to expect from this weave—it’s stiff, incredibly hard-wearing, and a beast to break in. In fact, due to the tight plain weave and the enhanced durability and water resistance provided by the paraffin wax-soaked coating, we’d argue that this is our toughest fabric to date. However, this also makes it a very stubborn fabric to work with, requiring certain seams to be hand-stitched when the fabric folds are too dense for our machines—or, quite commonly, when an attempt at stitching breaks a needle. This time-consuming construction process means this model is only available in very limited numbers, with each jacket displaying subtle variations in stitching—some even bearing visible scars where a needle fell victim to the heft of the canvas.
