Goodbye, Cotton. Hello, Comfort. Mizzen and Main specializes in shirts that are made out of performance fabrics allowing them to breathe, stretch and wick away moisture. They require no ironing, no dry cleaning, and are machine washable. These aren’t the shiny, polyester shirts your weird uncle wore in the 1970’s. This is 22nd century level. They’re made out of performance fabric. Yeah. Performance fabric. 0% cotton. 100% comfortable.
