The Kühl Tropik Shirt features Airflow 100% organic cotton. The open weave wicks moisture and keeps fabric away from your skin to increase air circulation. Featuring a crinkle effect in the fabric and contrasting back yoke inside the collar, the stylish Tropik keeps you cool and comfortable in hot, humid conditions. The button-down Tropik features Kühl signature metal buttons and a left chest pocket. Wrinkle resistant.
