Description
Nano Silk 50D / 12/0 is the first choice of professional fly tiers worldwide and widely regarded as the finest GSP tying thread on the market. It offers exceptional strength relative to its diameter, lays perfectly flat, and gives you total control — from ultra-small dry flies to larger nymphs and streamers.
Despite its extremely thin diameter, Nano Silk is 10× stronger than steel of the same thickness and virtually unbreakable. This allows you to tie hard, tight, and precise without worrying about thread failure.
Perfect for small flies — surprisingly versatile
50D (12/0) is ideal for flies in sizes #8–16, yet fine enough to be used all the way down to size #32. Because the thread lays completely flat, it creates no unnecessary bulk in heads or bodies — even after many wraps.
Nano Silk is also very easy to split, making it perfect for creating ultra-thin dubbing loops and for tying modern, highly detailed patterns.
