The proposition is simple: big weight, classic indigo denim made in America at the best values we've offered for a workshirt like this. We're making it easy to try a rugged workwear icon. Built to last and sewn right in the USA too. Enjoy this one - the American One Five Workshirt.
Good old fashioned raw denim. Burly at 15 ounces with tons of starch, this denim feels bomb-proof, particularly in workshirt form. It's ready for anything you throw at it. All the details are pure and classic. An indigo warp pairs with a crisp white weft. There is a big amount of weft show-through which helps bring the color to life. It also highlights the rare lefthand twill weave. Over time, some feel the lefthand twills develop a more supple feel, but you'll have to earn it with this version. You see nice grain and texture throughout. We treat it to a classic contrast denim thread. It's a complete, big weight American denim package at a massive value.
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 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 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 are 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.

What Customers Are Saying
"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."
-Anne F. | Verified Buyer
