This Nylon U.S. American Flag is second to none. The base fabric is specifically for active outdoor use with tremendous strength retention under UV exposure. It flies in the lightest breeze and provides deeper, brighter colors that will last over time. Flags 8 ft. x 12 ft. are finished with canvas heading and roped heading for extra strength and six or more rows of lock stitching with back stitch reinforcements. Flags 15 ft. x 25 ft. and larger feature corner patches on the fly hem. All our US flags are made in the USA.
