Today we're rolling out more specialty fabric we discovered from one of our favorite mills in Japan. A rare diamond quilted denim in a double weave construction for added density gets treated to a rich and inky double indigo coloring. This is the Diamond Quilt Workshirt.
We recently hit on a cache of more experimental styles from Japan. They showcase some of the more unusual techniques the mills are exploring. We like the results. These start with a classic quilted top. The small diamond pattern lends the denim surface a completely fresh texture and appearance. Small enough for style, big enough to add character. This version gets a double indigo top. A rare double weave construction in which multiple warp and weft yarns get used serves to add density and bulk to the style, giving it a sturdy feel. Soft and with great volume, this is a truly fresh style.
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 the ideal combination we're always searching for.
There are a number of construction details that 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 triple-needle 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 now.
