This is a classy plaid shirt that never goes out of style. I feel like I'll be wearing this same shirt for years to come. It's also wonderfully warm and cozy like your favorite blanket.

Drapes well. Warm shirt.

Jonah V. (Denver, CO)

Thick and heavy. Perfect fabric for a warm flannel.

Mouliné yarns are made by twisting together fibers of different colors. The result is a multi-color yarn that, when woven into a finished fabric, has a depth and subtle heathering not found in typical fabrics.

We worked with the famous Portuguese mill Somelos Tecidos to weave these heavy, yet incredibly soft flannels. The designs in our Mouliné Flannel collection are subdued and elegant—you won’t be mistaken for a lumberjack in these.

The Willamette is a large-format tattersall of grays and a closer look reviews a distinctive mixture of black, gray, and white due to the mouliné yarns.

How it's Made

Fabric Mill


Somelos was founded in Portugal in 1958, first making yarns and later adding cotton fabric production to its repertoire. The family-run business has become the benchmark for yarn-dyed men's dress shirting in the global market, and weaves fabric for many of the top brands and designers in menswear.


We’re proud to make our shirts in a facility in North Carolina that’s been making shirts continuously for 55 years with a history of quality and craftsmanship. The factory is a union shop that employs several hundred skilled operators, who earn a living wage. Every shirt made by Ratio includes over sixty operations performed by a dedicated team of made-to-measure specialists.
