A classic workwear fabric, a luxurious blend of fibers and special twist of color. It's hard to ask for more. The full range of Rainbow Nep Shirts is finally here. Enjoy.
We love when a mill starts with an iconic workwear style and lavishes it with top tier fibers and artistic finishes. Today is a true showcase. This is a theme that has created our top selling T-Shirts, but today we present a more refined garment. The start is a workwear classic - the chambray. Timeless and with historic utilitarian roots. This version blends cotton with linen to create luxuriously soft hand. Nice for warm weather use, a loose weave further enhances the comfort of these shirts. The finishing artistic touch makes the style. Nep yarns containing a rainbow of colors produce a tapestry of organic, colorful dots throughout the surface. Visible, but not over the top. A nod to true fabric craft. A highlight that demonstrates you're not wearing an ordinary shirt, but something more special. 
Our short sleeve button-up fits just like the long sleeve. It shares the same beautifully tailored body, not too slim, but fitted. High armholes keep the body lines clean. A very gently scooped bottom hem that works wonderfully, un-tucked or tucked. A no-button collar that’s perfectly sized to sit well.
We labor over every construction detail. Extensive single needle stitching is used throughout. All our closures are made from true mother of pearl. The front placket is also pleated, made the right way, using a true two piece construction. The feel is more substantial and the effort higher, but it's the right way. A rounded chest pocket completes the front.
Button-up shirts that are made in the USA using our quality of material and construction are typically priced much higher. The Gustin model, with your support, lets us do better.

What Customers Are Saying
"I wanted to tell you how much I love the rainbow nep natural t-shirts. After over a year of trying to find my everyday t-shirt, this is finally it. I have four of them now and they are basically all I wear."
-Anne F. | Verified Buyer
"So grateful for this brand! Love the fit, finish, and quality of everything I've ever bought from here. Moreover, the pricing enables people like me to have access to quality goods which are often outside of the reach of the most working people."
-Joshua 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."
