City Hat can be made in a short version ready to pull from your pocket on a cold night, or with a large cuff so it stays on your head in windy weather or when you are out biking.

The difference between Medium and Large is the circumference, which means Large has room for a big hair or fits a large head, while Medium fits most adults, both men and women.
