Peter Millar Dean Performance Flannel Sport Shirt in Fatigue

This shirt gets the look right first: a brushed, natural hand that mirrors classic cotton flannel, then adds what flannel can't offer on its own, thermoregulating comfort and real stretch, built from a performance fiber and viscose blend instead of heavyweight cotton.

That distinction matters most in the care: where a traditional flannel demands careful washing to avoid shrinking or fading, this one is built for easy, everyday laundering, so it holds up to being worn as often as its look deserves.

Fatigue is a season-ready neutral that layers naturally under a jacket or works on its own through fall and winter. It's the shirt for a man who loves the flannel look but doesn't want to babysit the garment to keep it that way.
