This is a mostly wool cap with some thin stripes in warm brown alpaca and gray wool/opossum down blend that comes from New Zealand.  The black is dyed.  The rest is the natural color of the fibers.  The dark brown is Romney wool.  The black is Corriedale wool.  The dark gray thin stripes are Merino wool.  The medium gray thin stripes are English Shetland wool.  The very light gray (that looks white) and the lighter medium gray thin stripes are wool/opossum down blend.  The warm brown thin stripes are alpaca.
