Our fully sewn & embroidered, polyester American flags are our heaviest and most durable American flags. They are crafted from top quality, heavy duty 2-ply polyester. It's the toughest flag material available. Color is deep and rich and the finish quality is unsurpassed. Each flag is fully sewn, not printed. Recommended for windy applications or where maximum wear-life is desired. For less windy or less demanding environments we generally recommend our sewn nylon American flags.
