Finally, a shirt that combines the crisp feel of Wrinkle-Free cotton with the power of Performance. It’s the best of both worlds—breathable, stretchy, and sweat wicking, all while keeping that polished look you love. Even better? It’s machine washable, so you can skip the dry cleaner—and stash the iron. We designed this classic gingham pattern to easily pair with a sharp Italian sport coat or stand out on its own. And to seal the seal, we infused it with micromineral technology to keep you cool all day long.
