Weighing in at 8.7 ounces, the Eugene Heritage flannel has old school cool written all over it with its heather navy, red and khaki plaid. It's made out of the softest heather brushed twill flannel out there. What makes it extra special? Grayers designs all of their own stripes, patterns and plaids. We weave our own fabric. And our fit is on point. Wear it open like a work shirt or buttoned-up.
