A/c ShirtWe make our venerable A C Shirt with a breezy 100% organic cotton fabric (that feels as good as an open schedule) to offset the effects of equatorial heat and humidity. The ultimate warm weather performance shirt, its crepe like fabric features fast wicking properties and an open weave provides maximum airflow. It has a button front placket, a button through chest pocket and side vents at the straight hem to allow a greater range of mobility.
