The hat features our highest crown with a broad, seamless polyester foam front. 5-panel design has a mesh-polyester back to circulate airflow. The flat brim is made of 100% organic cotton canvas, with a moisture-wicking COOLMAX(R) fabric headband to keep you comfortable and dry. Adjustable snaps in back secure the fit.
