These polyester Air Force flags are made of a 2-ply polyester material and are all made in the USA.  These flags are meant to stand up to high wind areas and are the strongest Army flags offered.  They have lock stitching on the fly ends to help reinforce the flag and helps add to a longer lasting flag.  The flag is the official design of the United States Air Force and the colors are extremely bright.  This flag reads correct on one side and reverse on the other.  The flag is finished off with a strong polyester white heading and brass grommets
