Semperfli, developers of Nano Silk, one of the strongest and best regarded technical threads for fly tying have applied their skills to classic waxed Polyester threads. Using the similar manufacturing techniques as with Nano Silk, we extruded thin polyester strands. Twisting the strands lightly enables it to both lay flat and split easier than other threads on the market. Semperfli has extended the capabilities of the fly tyer even further.
