This flag is made from spun polyester, one of the most durable flag materials on the market. The open weave reduces fabric stress and resists high winds. These flags are the best choice if you fly the US flag 24/7 and the flag will be flown in an area with high wind speed. As these US flags are made from heavier fabric, they require a higher wind speed to "fly" than nylon flags. Also they require more effort to put up and take down. The 2-ply polyester looks like a coarse cotton. All these US flags have sewn stripes and embroidered stars and roped canvas headings with thimble ends. They are designed for outdoor use and will resist fading and fraying. These top quality 2-ply polyester flag are all 100% US made using a special high tech fabric. This flag size is suitable for flagpoles from 35ft to 60ft. Also consider Nylon US flags, which are lighter to handle and fly in lower wind speeds. They are also significantly less money to buy. On the other hand, a nylon flag will fray before a spun polyester flag.
