Bison down is a very warm, insulating fiber. It is also very durable for such a soft fiber. It has a moisture regain of about 30%, compared to 18% for sheep’s wool — this means that even when saturated, the fiber draws moisture away from one’s skin.
There is only a limited amount of fiber available – estimated at 10,000 pounds per year versus 2,100,000,000 pounds of sheep wool.
Bison wool is harvested in Colorado and South Dakota, as a by-product of the bison meat industry.
Most bison wool clothing is rustic in styling. The Fox River products tend to be the softest.
