Underrated Fiber Series: Bison Wool

In our underrated fiber series, we will be featuring products made with wool from alpacas, llamas, vicunas, bison, musk oxen, and yaks.

Let’s start this series off by looking at Bison wool, which is harvested from buffalo in Colorado and South Dakota each spring, when the animals shed their fur.

Bisons were almost driven to extinction, but today they are making a modest comeback, with several ranches raising Bison for their meat, and a few ranches harvesting their fiber as well.

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.

Bison Wool Summary

A short and quite fine fiber that offers unusual durability for its level of softness.
