Product details:

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