Our American flags are the strongest, longest lasting banners available. They are made of tough 2-ply 100 percent polyester. These American flags withstand wind, sun, dirt, and moisture because of the extra rugged, strong weave. They are excellent for industrial/institutional use. All sizes have finished appliquéd stars and sewn stripes for extra long life. Each is equipped with a grommet, so it able to fly immediately. They are light weight offering maximum flying ability, yet are open mesh, which reduces wind resistance, thereby lessening abrasion and increasing the American flags life.
