This an extra long medium bulky weight round cap that is designed to fully cover the ears.  It's made from Corriedale and Romney wool, mohair, tussah silk and tencel.  The blue and dark teal blue are Corriedale wool.  The green is fuzzier textured Romney wool.  The variegated pinkish lavender stripes are mohair.  The lighter shiny green, navy blue, purple and teal accent stripes are tussah silk.  There are also some very thin hard to see purple stripes in tencel.
