Similar to cashmere, yak down fibers are a fine,
soft protein fiber. They are just over an inch long and are combed
or shed from the yaks that are a Tibetan plateau specialty. They
are then de-haired for the yak down.
Its short staple length makes it a challenge to
spin in its pure form; therefore, it is often blended with longer
staple fiber such as wool, hemp and silk.
