Details Pole not included. Happy Cow premium-quality flags are soft yet durable. Each flag is made from two panels of heavy-duty soft polyester with an exclusive sun-block backing to enhance the rich, vibrant colors of each design. The genius 2-ply design is weather, mold, mildew, and UV-fade resistant. We make our flags double-sided, so you can enjoy them from any angle. We use a process called dye-sublimation printing to ensure that your design is printed with the best quality. See our FAQs section for more information about our printing process. Our double stitching technique makes our flags highly resistant to fraying and ripping, so you can enjoy them season after season.
