Outdoor flag material recommendation

Hello everyone, we are looking to do some banners similar to this and wanted to see what recommendations you have for durability. They might be single pole like the image or pole on top and bottom. Is there such product that can give me 2-3 years in normal conditions?

Thanks

 

That's what I was wondering, for most part I would think 6 - 12 months. I know we used Marine canvas or similar to awning material but it not the same as flag material.
