What material is most durable for outdoor flags?

The Battle Against the Elements

Outdoor flags take a beating from UV rays, rain, and relentless wind. If you want a flag that lasts, you need the right material.

Spun Polyester (2-Ply Polyester)

For traditional horizontal flags flown on a pole, spun polyester (often referred to as 2-ply polyester) is widely considered the most durable material available. It is incredibly strong, features an open weave to let wind pass through, and is ideal for high-wind areas.

Airmesh / Mesh Polyester

For custom printed promotional flags like feather flags, Airmesh (Mesh Polyester) is the pinnacle of durability. This material has tiny holes engineered into the fabric. These holes allow wind to pass directly through the flag, significantly reducing the stress on the fabric edges and the flagpole.

Nylon

While nylon is an excellent, lightweight material that flies beautifully in the slightest breeze, it is generally less durable than spun polyester or airmesh when exposed to constant, heavy winds.

Conclusion

If longevity in harsh Canadian weather is your primary concern, opt for Spun Polyester for traditional flags, and Airmesh for custom promotional banners.
