Flags and banners are silky soft yet shockingly durable. Each flag is made from 2 panels of heavy duty soft polyester with an exclusive sun block backing to enhance the rich vibrant colors of each design. The genius 2-ply design is the weather, mold, mildew, and UV-fade resistant. Most importantly, it's just heavy enough for a picture perfect drape and graceful movement. Double stitched not only is the outside perimeter and each corner neatly double stitched, but the ends of the sewn-in rod pocket at the top of the flag are also as well so they will withstand the test of time. Flags galore top quality flags are highly resistant to fraying and ripping season after season.
