Annin Nyl-Glo house flags are made of special SolarMax Nylon fabric to guarantee long lasting flags with brightest colors. Annin offers a 1 year guarantee for color on all NYL-GLO ColorFast flags. Annin Nylon house flags are constructed using 200 denier nylon, which is denser and better resistant to UV light than other nylons. Annin Nyl-Glo flags are very lightweight and fly even in the smallest breeze. You can find our selection of house flag poles and accessories here.
