This is a bulky weight hat designed to fully cover the ears with the brim turned up or down.  It's made from several types of wool.  The gray brim and wide stripe at the upper center of the hat are actually two slightly different grays.  Both are Jacob wool.  The teal green and thin accent stripes in beige, purple, and pale blue/gray are all Corriedale wool.  The brown is undyed Romney wool, and the olive green accent stripes are the same Romney overdyed with green.  A nice, warm hat for colder weather.
