A friend of mine weaves things from buffalo wool- the wool is not shorn from the animals, it is collected whent eh bison scratch their backs on barbed wire fences during the one time a year they shed their thick winter wool.
A friend of my husband’s who had been a rodeo rider wore a little talisman that contained a tuft of buffalo wool. It is the softest wool I have ever felt and that includes alpaca. I danced with him once and he was the smoothest dancer I have ever experienced, I guess that’s why he could stay on the bulls.
