The saturated blue and purple hues on the Irving Plaid match the twill fabric's rich depth for the most dapper of high-quality dress shirts. We love the the Irving's sharp look with a dark suit—it works wonders under gray—but it's just as cool with jeans in the right rinse.

The Irving is made in our Madison Twill, a European-woven fine twill made from 100’s two-ply yarns -- our top-of-the-line dress shirt quality. At 129 GSM (that’s “grams per square meter”), it’s light enough to wear year-round, but with just enough heft and density to make it stand up to the rigors of a 12-hour day.

Mileta’s world-class fabric finishing and fine twill weave give it a chemical-free wrinkle resistance that adds to its long-wearing durability and clean drape, ensuring you’ll look sharp from early mornings to late nights.

Awesome pattern, super comfortable.

One of the first Ratio shirts I purchased. Fairly lightweight but still soft to touch. Wear this one all of the time for work.

This is a great fabric and shirt. I like the colors and it is very comfortable. Good all year round.

Fantastic plaid that dresses up and down great, fabric does a great job of not showing any wrinkles and survives in a suitcase well
