Annin Flagmakers has been synonymous with high quality flags for almost two centuries. And not only that, Annin has played a role in key moments in U.S. history, from presidential inaugurations to major military victories and even space exploration. And so it's no wonder that Annin is the company behind American flags made with the extremely durable Tough-Tex material. As the name implies, this is a flag that is as strong as the state of Texas itself. And that's in part because it has a two-ply, spun-woven polyester fabric that is particularly adept at resisting high winds. It also boasts an open weave to reduce additional fabric stress. Like many Annin flags, the Tough-Tex flags come with a colorfast guarantee for one year, which is perfect for large outdoor flags that are flown daily.
