This flag is silky soft yet shockingly durable. Each flag is made from 2 panels of heavy-duty soft polyester with exclusive sunblock 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. top-quality flags are highly resistant to fraying and ripping season after season. Through dye-sublimation printing, flags are hands-down gorgeous. Arlmont & Co.
