U.S. Flag Store's Embroidered Polyester 20' x 30' American Flags are made in the USA. Featruing large, appliqued stars and stitched stripes, these are traditional, quality American flags - they are not cheap imports or printed flags! These flags are made with 2-ply polyester which is the strongest flag material available. Since polyester flags are extremely durable, they are recommended for flying in parts of America with lots of rain and high wind. If you live in a milder part of America, U.S. Flag Store recommends flying a Nylon American Flag.
