Veevus GSP Thread (Gel Spun Polyethylene) is the strongest fly tying thread on the market.
It differs from other brands in that it was designed with a slight twist, preventing it from opening up, and thereby making tying with it a breeze. Veevus GSP lays flat and is the smoothest thread for spinning deer hair.
Each spool contains 65% more thread than other offerings on the market.
