A flat cap is a rounded cap with a small stiff brim in front, originating in Britain and Ireland. The hat is known in Ireland as a paddy cap; in Scotland as a bunnet; in Wales as a Dai cap; and in the United States as an English cap, Irish cap, or flat cap. Various other terms exist (cabbie cap, driver cap, longshoreman cap, ivy cap, train engineer cap,etc.). Cloths used to make the cap include wool, tweed (most common), and cotton. Less common materials may include leather, linen, or corduroy. The inside of the cap is commonly lined for comfort and warmth.
