This is a  medium bulky weight mohair and silk hat that fully covers the ears.  The body of the hat is extra soft kid mohair with thin accent stripes in tussah silk.  Some silk has been blended in with the mohair also.  The olive brim is some very curly yearling mohair that has been spun to accentuate the curls.  It's also very soft, but with an extra bit of texture.
