Wapsi | Ultra GSP 50 Denier Thread White

Ultra GSP is the strongest fly tying thread on the planet. Boasting a steel like strength for its weight, this thread really lets you put the pressure on! Our gel spun polyethylene is supple, ties flat and is available in the largest selection of sizes and colors. Choose 50 denier GSP for tying small trout flies with a minimum of bulk. GSP 75 and 100 have all around versatility for fresh and saltwater flies.

This is the strongest thread available. I use this thread for spinning Deer hair and any other job that requires a lot of thread torque.
