This 100% cotton bonded flannel shirt with a polyester microfleece backer insulates against a cool fall/winter chill. Fondly referred to as the "shop shirt" at Stiop HQ, the Pertex® Microlight Minirip Nylon toughens up the elbows and undersides of the cuff and custom-engraved metal snaps adorn the chest pockets and cuffs. We've designed this zip flannel to fit like a shirt, for jacket type fit, you'll want to size up.
