What is the difference between Dry Fly Polyyarn and Semperfli Traditional Polyyarn?

Nicknamed by fly tyers world wide the 'floating yarn'. With a very specific gravity / density of 0.91g/cm3 Polypropylene Yarn is lighter than water which means that it floats making it ideal for dry flies.

Polyyarn Structures

The big difference in the Polyyarn products are the material structures:

  • Semperfli Dry Fly Polyyarn is a tightly bonded, crinkled polyyarn which when has a very ‘buggy’ nature. Its structure enhances polyyarn floatability as its fibrous design traps micro air bubbles around the surface of the material.
  • Semperfli Polyyarn is a loose, continuous fibre making it perfect for wings, posts on parachute flies and dubbing.

This new range is specifically designed for dry flies for bodies, however it can be teased to expose the base fibres in the materials which can be used loose or as dubbing. Because Dry Fly Polyyarn is bonded we have been able to blend different colours together to make a more natural body material, after all no insect or fly is a single colour.

This material is ideal for new, amateur fly tyers being simple to wrap onto a body using Nano Silk or Classic Waxed fly tying threads. For advanced fly tyers the fibres can be teased apart and even be used as dubbing.
