Sierra Flannel
Our Sierra Flannel is cut from 100% cotton flannel and laundered for a soft, broken-in feel from the first wear. The shadow plaid gives each colorway depth without getting loud. It has a relaxed fit, two flap chest pockets, custom WillBo buttons and our signature sleeve label. Wear it over a tee on cool mornings or under a jacket when the weather turns. It’s the kind of shirt that gets better every time you reach for it.
Available in Denim, Fog and Sky / Blue.
