Another absolute beast workshirt designed for those seeking an indigo alternative. Rugged, heavy, double black selvedge from Japan done up in vintage American workshirt style. It's an ideal pairing and one you can wear hard for years. Yes, you'll have to earn it, but the wear-in work is worth it.
Color and weight come together in this style to create one of our heartiest workshirts yet. A jet black warp and weft create a super saturated black surface - nice pairing with blue denim or our chinos. You can see the vertical grain on the surface from a textured warp yarn. At 14 ounces with lots of starch, this fabric gives the workshirt a truly bomb proof feel. It's all here in truly rugged form. Get ready for a challenge.
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.
For production on these, we're teaming up with a small shop that exclusively sews reproduction workwear for Japanese brands - always above $300 per shirt. Their work is immaculate, and we're excited to be partnering with them.
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.

What Customers Are Saying
"My 1968s came in the mail yesterday…They're amazing! From the fit (thank you for all the hand-holding!) to the detailing, I'm blown away. Just tremendous quality at any price point, but the value here is off the charts."

-Curtis C. | Verified Buyer
"About a year ago, a coworker introduced me to Gustin (he rocks some of your pants to the office on the regular) and I have been watching the releases ever since. About three months ago, I finally backed a campaign. Since then, I have been so happy with all the pieces I have received."
