The heaviest Moleskin we've used treated to our vintage workshirt style makes for the ideal match. This style perfectly captures everything great about true high quality moleskin from the ruggedness to the pliable felt-like comfort. This is the Japan Heavy Moleskin Workshirt.
Moleskin can feel more fitted than denim workshirts. Size up if in between sizes.
Of all the Moleskin styles we've offered and seen, this one immediately got our attention. That's why we used it in 5 Pocket form and why we knew it would be a must own workshirt. It simply represents everything this classic style represents. Most notable is the way it combines ruggedness and refinement. We know Moleskin has a history as a utilitarian, hard wearing fabric. This version instantly builds that personality with real heft. At 15 ounces, it's the heaviest version we've offered and you feel it. Burly and thick. Refinement comes in the form of pure felt-like suppleness, approaching a thick leathery hand. It's a truly special combination that makes this great Moleskin stand out. You feel comfortably protected in this burly style. Army Black is truly versatile. Love is first sight and touch.
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 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. They’re a deep navy shade with a slightly domed top and two holes for securing. 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.

Customer Feedback on #121 JAPAN HEAVY MOLESKIN WORKSHIRT - BLACK
"6’2” and size Large fits a treat. This shirt is more like a shacket. It is crisp and formidable. Only worn it once so once it breaks in I’m sure it will soften up and get into “shirt” territory. Looks sharp AF either way."
