Men's 100% Cotton Flannel Plaid Shirt

The Flannel Shirt, Done Right

100% cotton flannel — warm, breathable, and gets better with every wash. This long-sleeve plaid shirt has a classic turn-down collar and single-breasted button front, making it the kind of piece that works just as well thrown open over a tee as it does buttoned up on its own. The smart-casual cut means it moves easily between everyday wear and slightly more dressed-up moments.

Available in a wide range of plaid colourways, in an extended size range from size 38 up to 44 (equivalent to S through 4XL).
