The Ampal Creative loves vintage felt pennants, especially from the 30s-60s. Thick screen printed hand designed graphics celebrating everything from your town or team, racing, events, brands, etc. They tried to capture that feel with a series of hat-sized pennants celebrating areas that are special to them. They had a ton of other ideas, so don't feel neglected if they didn't nail your area on this first run.
They chose khaki color for the micro herringbone underbrim and the lining - the vintage racing world always had a lot more khakis than denim and I've associated it ever since. The unstructured upper and leather strapback complete the look.
