Carefully constructed of the strongest and longest-lasting nylon material available, this version of Old Glory offers stellar resistance to UV damage and can fly high for hours without fading. The lightweight nature of the nylon also ensures the flag dries quickly after a downpour and flutters in the slightest of breezes. That means the flag keeps on waving rain or shine, or at least soon after a rain, following the tireless American tradition set forth by the U.S. postal service.
