LOON ERGO UNDERFUR COMB – Spinning and stacking hair like a boss means including just the best hair. Underfur has no business making its way onto your flies, and the Ergo Underfur Comb is the best way to make sure that it stays out of the mix. The fine metal tines stand up to unruly pelts, making it easy to separate the fibers you want from the ones you don’t.
