In the Autumn of 1775, Commodore Erik Hopkins readied the Continental Navy on the Delaware River. The signal to attack the British Navy came in the form of a striped jack. The uncoiled rattlesnake represents America's willingness to strike when provoked. Today the flag flies on all U.S. Navy warships. Designed by our staff in New Bern, NC. The Don't Tread on Me flag hat has a Salt-Wash™ to create a weathered, heavily sun bleached look.
