Using similar techniques as with Nano Silk Semperfli have extruded thin Polyester strands which are then slightly twisted and had a light amount of wax added to them.
 
The amount of wax added has been specifically applied after consultations with top Professional Fly Tyers.
 
With the lightly twisted strands this allows the thread to both lay flat and split easier than other threads on the market.
