Similar in style to the Scottish tam-o-shanter, the Irish scally cap provides no protection from the sun, but coves the top of the head from the cold, and has a small front brim. Mostly found in leather or wool. During the 1980's was a trend in places such as Australia and the US and Canada.
"Is that a new scally cap you're got on your head, John?"
"Aye, made o' the finest grey wool."
