Semperfli Nano Silk 300 Denier Hair Stacker Thread
This a great thread for saltwater flies and stacking hair. 1/0. 109 yards. White.
Pro Tips:
1 - rotate anti-clockwise to untwist and lay perfectly flat. With just 2 or 3 light wraps of Nano Silk over foam you can then tighten and tie in foams or materials without cutting them.
2 – use white Nano Silk and simply color the last 4 inches (100mm) of thread for the desired head color.
