This is a medium bulky weight cap designed to fully cover most to all of the ears.  The gray main color is undyed Jacob wool.  The blue stripes are Corriedale wool, and the lighter gray near the top is Icelandic wool.  The darker gray variegated stripes are a blend of black Merino wool and malamute hair, which adds a bit of soft fuzzy texture.  This hat has a wide circumference, so is probably too bid for a child.
