Our flag material is very strong, durable and weather proof. We compared it to the competition's, and after a 8 hour test in the rain at 65 mph ours held up, but their's did not. We secured the flag at the top and bottom to keep it from bunching up at high speeds. We have used high test upholstery thread to attach the flag. This thread will not unravel or break. There is also a rubber topper to keep people safe and reduce the risk of the rod splitting when hitting trees and other outdoor material. We can also have you logo screened onto the flag. Since our flags won't bunch you will be able to read you logo nice and clear.
