What makes the perfect flannel? For us, it’s softness. Our hunt for the perfect flannel led us to the Portuguese flannel experts at Somelos, where we developed our new exclusive Mesa Flannel quality.

It’s brushed on both sides and woven with beautiful heathered yarns to make it incredibly soft. We also chose finer yarns than you’ll typically find in a flannel, which makes it both softer and lighter than expected.

This is the kind of flannel you can break out during Indian Summer days and wear it all the way into spring. Layered-up or worn on its own, the Olive Mesa Flannel is the perfect complement to your fall wardrobe.

Great shirt, thicker and warm, definitely a winter shirt.

Dominic P. (Thorton, CO)

This heavier flannel feels great in the cold. I love the firm collar and the fit is unreal man. I haven't actually used the pockets but like how they look. Rolling up sleeves can be hard with how good the fit is, and how skinny my arms are and boney my elbows are.

Rishi S. (Denver, CO)

A very soft mid weight flannel. Easy to wear and care for. The color is very versatile - jeans, khakis etc.

Ratio Customer (Irvington, VA)

Super soft flannel. Very comfortable

Anthony L. (Arvada, CO)

Fairly warm, versatile fabric that pairs well with denim, khaki, blue or olive chinos well.

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 this shirt in a facility in New Jersey that’s been making shirts continuously for nearly 60 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.
