Hercules Poly has proven itself in the industry to be one of the better flag fabrics on the market. This unique fabric gives you added life, similar to spun polyester, but flies and gives one the look of a nylon flag. Hercules Poly is bright and beautiful while flying but it does not collect dirt and pollution as bad as other flag fabrics. These qualities enable the flag to keep its beautiful appearance over the life of the flag, it is exceptionally well suited for industrial, institutional, and commercial users that require added flag life with little upkeep. Hercules Poly is also perfect for the severe weather regions where a polyester flag is a necessity. Try it, you'll be glad you did.
