Since its invention, poly yarn has been used in many industries from carpets to seatbelts. However, for fly tyers its unique abilities make this a stunning fly tying material.

With a specific gravity/density of 0.91g/cm³ poly yarn is lighter than water and floats naturally. This quality makes it ideal for dry flies, particularly when used for parachute posts and as dubbing. When used on a dry fly, it holds the floatant applied to it and keeps your fly afloat.

  • Often referred to as floating yarn.
  • Ideal for bodies, parachute posts, indicators and as dubbing.

Each card holds 4 metres of poly yarn.
