POW/MIA extreme wear outdoor flags are produced using open weave 2-ply woven polyester, the longest wearing flag material available for daily, long-term display. This open weave material reduces fabric stress and outside fly-end shredding in high wind applications, increasing flag life over traditional nylon flags. Textile trade names are Annin Tough-tex, Eder Flag Poly-Max and Valley Forge Flag Spectrapro.
