Portuguese Flannel brings four generations of expertise to every shirt, and the Virgo is proof. Cut from a heavyweight wool jacquard—suiting-inspired fabric woven in Portugal—it’s got structure and warmth that go well beyond your average flannel. Finished with recycled polyester buttons, a chest pocket, and a rich plaid that feels right at home once the temps drop, it pulls double duty as an overshirt or a midlayer.
