Our nylon flags are the best money can buy. These SolarMax flags are made of an extraordinarily durable nylon that stands up to high winds, bright sunlight and UV rays. These flags feature a dense 200 denier nylon weave and premium quality stitching. They are also backed by our unconditional one-year colorfast replacement guarantee. Available in all sizes! These are double-sided flags in which the image shows correctly on both sides of the flag, versus single reverse flags on which the image shows correctly from just one side. This is the flag you want for flagpoles, where viewers are likely to see the flag from both sides.
