More About Semperfli

Semperfli makes precision fly tying materials designed by anglers for tyers who care about performance. The brand's flagship is Nano Silk, a strong, ultra-fine GSP thread that lets you tie flies that are both delicate and durable.

The Semperfli range

  • Nano Silk thread for fine, strong builds on small and large patterns.
  • Straggle String UV chenilles for buggy, light-reactive bodies.
  • Synthetic marabou, tinsels and wires for movement, flash and ribbing.
  • Dubbing and tungsten beads for bodies and weighting.

That breadth, paired with the brand's focus on innovation, makes Semperfli a useful choice for tyers creating effective, lifelike flies across freshwater and saltwater conditions. Whether you are after finer thread for tiny patterns, UV-active body materials for added attraction, or dependable beads for weighting nymphs, Semperfli delivers the precision serious tyers expect. To see how Nano Silk compares by denier, read our fly tying thread comparison guide.

What is Semperfli Nano Silk?

Nano Silk is a gel-spun polyethylene thread that is very strong for its diameter, allowing fine yet durable thread work.
