What are the most common flag materials?
A. Nylon and polyester. Both materials look the same from a distance. A nylon flag will fly better in a gentle breeze, since the fabric is lighter and more tightly woven. Conversely, a polyester flag is recommended for use in windy areas since it is heavier and will not “trap” the wind as easily. This reduces the “snapping” effect that is common in strong winds and prolongs the flag’s life.
