Qiviut is stronger and warmer than sheep's wool, and softer than cashmere wool. Wild muskoxen have qiviut fibers approximately 18 micrometers in diameter. Females and young animals have slightly finer wool. Unlike sheep's wool, it does not shrink in water at any temperature, but this means that it also is not useful for felting.
It is most commonly used for hats and scarves, and is among the softest wools. It is very expensive; a high quality knitted scarf can cost more than 300 U.S. dollars, but will last over 20 years with good care.
