A classic made new through the masterful use of a bold crosshatch grain that perfectly exposes a boldly tinted weft. This is the Indigo Acid.
We love a classic denim with details that make it fresh. When they all work together, the result is ideal. That's what we found for you today. The start is a deep, dark indigo warp. Expert use of weft and grain takes this style in a great new direction. The weft is a strongly tinted yellow. Normally, this could almost go unnoticed, but the mill has masterfully incorporated an intense crosshatch grain that allows this yellow weft to shine through boldly. The result is a classic dark indigo look with an acid yellow tint. Unlike anything we've run. Fresh, but still subtle enough to be enjoyed as a workhorse style. 
There are a number of construction details that define our workshirt. The first is ample triple needle work with a classic chain stitch runoff. Triple needle is a specialized stitch not found on a standard button down 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 “runoff” 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 side hem gussets. It’s a small functional element and looks absolutely great. Finally, we love the chin strap. Ours is small enough to be tasteful while still reminding you of the work wear 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.

What Customers Are Saying
"Just wanted to thank you for the jeans. I had high hopes and yet these exceed my expectations! I love the fabric, and I love the fit and construction. Nice, nice work."
-Jeffrey S. | Verified Buyer
"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."
-Scott S. | 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."
-Anne F. | Verified Buyer
