From the undercoat of the American plains bison, with just enough of the coarse fiber to give it some spikiness. Ultra light, and naturally water repellant, bison down holds bubbles better than almost any natural fiber. The down ranges from 16-21 microns, which allow you to dub down to a size 26 and beyond, perfect for dries and nymphs.
