Choosing between a rugged work shirt or a cozy flannel? Why not wear both? The flannel-lined work shirt as all the features you need in a work shirt, like fully functional pockets for storing what-nots (or frigid hands). Plus, we added a touch of stretch to the durable twill fabric, so you can twist and reach without busting a seam. And then there’s the soft lining — it’s 100% cotton flannel and feels broken-in from day one. Simply put, you’ll never have to choose between your favorite shirts again.
