Our original, most popular, and still most special super heavy selvedge finally gets paired with our vintage workshirt style. The result is an investment piece you'll enjoy and wear hard for years. Meet the Super Heavy Workshirt.
The Super Heavy is a true selvedge denim trifecta: huge weight, incredible comfort, and amazing fades. This is a combination that you rarely find in a single denim, and likely why this style is one of our most popular extra heavy selvedges of all time in denim form. It's equally great as a workshirt. At 18 ounces, this denim is squarely in the extra heavyweight class. In workshirt form, it takes on a shirt-jacket character. The moment you pick it up, you feel the brick-like heft. However, that's not all you feel. Even in raw form, the fabric is amazingly pliable. It's almost like soft leather. You feel tough wearing this denim, but you can actually enjoy it right on day one. That's a very good thing because the fades are absolutely gorgeous. It starts with a bright indigo shade that's a bit lighter than a traditional dark indigo. It has a more open weave that brightens the overall look further. Great grain emerges on a sweet medium blue base. This is for the true workshirt fan.
Our workshirts are true throwback garments. Inspired by the style's origins of utility and ruggedness. Finding fabric with the right character for this style is key, and we have fresh new examples today. Each starts in a truly superheavy form. Heavy cotton yarns woven loosely give this fabric the ideal balance of heft with a pliable, soft hand. It's that ideal combination we're always searching for.
Several construction details define our workshirt. The first is ample triple needlework with a classic chain stitch runoff. Triple needle is a specialized stitch not found on standard button downs and that serves as the heart of any good work shirt. Ours gets a triple need flat felled yoke and side seams with chain stitched bottoms. We also allow the side seam chain stitch to “run off” the end, giving you three chain stitch ends on each side. We bar tack to ensure the runoff can’t compromise the security of the side seam. The second detail is double chest pockets. We keep ours a bit cleaner, without flaps, but use button closures and double bar tacks in each corner for added strength. The left chest pocket gets the addition of a small pen slot. The third detail is the side hem gussets. It’s a small functional element and looks absolutely great. On our selvedge styles, we incorporate the selvedge on the bottom. Finally, we love the chin strap. Ours is small enough to be tasteful while still reminding you of the workwear roots of the garment. We created new custom Corozo buttons specifically for our work shirts. Overall, this is one of our most intricately constructed garments and one of the most costly to produce.
Our workshirts will be available in our Classic and Slim fits. The main differences in details between our workshirts and our other shirting come down to construction - no back box pleat, and differently shaped side scoops. The Slim fit has a more tailored body as compared to our Classic fit. Chest and waist come in to provide a more fitted option. Details are in our fit guide.
