Look and Feel:
Nylon is lightweight and shiny. Its texture is slightly rough, and somewhere between fabric and plastic. On the other hand, polyester has a completely matte surface. It looks and feels like cotton, rougher and heavier than nylon and without a hint of shine.
Frequency of Flight:
When choosing between a nylon flag and a polyester flag, it is important to consider whether the flag will be outside 24 hours a day, from sunrise to sunset or just on holidays. In general, polyester is a better and more durable choice for more frequently flown flags. Nylon Flags are lighter weight than polyester – so are great for the occasional outing, as they are easier to fly.
Nylon is lighter than polyester, and therefore flies more easily in areas without high winds. It is a better choice for areas like the suburbs. However, if you live by the sea or in another place with high winds and wet weather, polyester is a better choice. Polyester Flags are slightly heavier, but are more resistant to weather conditions. These are great as something you may want to leave outside for short periods of time.
•If you wanted to have a flag to tie to a pole, like perhaps for your club or group, a nylon flag would be the better choice, as the lighter weight requires minimal wind to make them fly.
•If you wanted to have a flag to hold, or wrap around yourself at a Chargers game (Editors Note: IN SAN DIEGO! GET OUTTA HERE WITH THAT L.A. BUSINESS), a polyester flag would be a better choice, as it is slightly stronger, and more weather resistant.
However – if you are buying a flag to hang in your bedroom, lounge room, shed or any other indoor place – either fabric is fine.
