Relaxed and ready for any season, meet the future of flannel. Our Performance Flannel Button Down combines the classic cozy feel you love with some seriously technical upgrades. Thanks to an award winning nano-fiber called graphene, this shirt can keep you warm without feeling heavy and cool things down when it gets hot. Plus, it fights static and stays fresh longer. The modern plaid design looks great, and the soft fabric lets you move easily. With moisture-wicking features and a relaxed fit, it’s your perfect go-to shirt for any season.
