3/0 UNI-Thread serves the fly-tier who regularly ties on hooks larger than size #12. It is of the same material as 8/0 and 6/0 UNI-Thread, but with an increased number of filaments.
6/0 UNI-Thread is a general fly-tying thread of continuous polyester filaments. The wide range of twenty-five colours meets virtually all fly-tying needs. UNI’s exclusive waxing process produces a thin coating to reduce that annoying build-up of wax in your bobbin tube.
8/0 Midge Waxed UNI-Thread is the favorite fine fly-tying thread of fly –tiers all over the world. Noted for being exceedingly strong for its diameter.
