Outdoor Montana state flags are available in a variety of size, material and mounting options. Nylon Montana flags are lightweight but durable and dry quickly after a storm. For a more heavy-duty Montana flag, choose the heavy-weight polyester flag. The heavy duty polyester requires more wind to fly, but also lasts longer. Please call us if you don't see the size or style Montana flag that you are looking for. We can find, or custom make the perfect flag for your display.
