For large banners that you might see on the side of buildings, or in other situations in which wind might be a factor, vinyl mesh banner fabric is great solution. The material is lighter and easier to handle than solid vinyl and is far less likely to wrinkle, so it’s also easier to ship and store.  Not good in situations where the banner will be backlit, since the image tends to disappear.  Finishes with hems, grommets, pole pockets, etc., just like regular vinyl banners.  Slightly more expensive than solid vinyl in small quantities.
