This is a strong, waxed fly tying polyester filament thread for larger flies. Measures 220 denier and has a breaking strength of 32 oz. 100 yd. spools. This thread would fall into the round thread category. One of our staff favorite tying thread.

This thread is great for tying with bucktail and many other materials as it does not tend to slip or "waterfall" over cut material ends which can aid in your flies having cleaner heads.
