Most flags are made of either Nylon or Polyester. Both Fabrics are good, but they have there differences.
Nylon Flags are lighter weight than polyester - so are great for the occasional outing, as they are easier to fly. They also have a "shiny" appearance.
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, while you are at the races or motor sports event 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 soccer or cricket or football match 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.
