Wapsi Beaver Fur is a versatile material suitable for various applications when tying flies. The soft medium length guard hairs work well for tails on nymphs and dry flies, and can also be spun creating "buggy" nymph bodies. Beaver fur is also popular for making collars on wet flies. The warm gray underfur makes great dubbing for small dry flies. The natural oils make this fur water resistant and fast drying.
