Semperfli Poly Yarn

Color: Cream

Often nicknamed by fly tyers as yarn dubbed as the "floating yarn". 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 0.91 g/cm³ Cream poly yarn is lighter than water and so floats making it ideal for dry flies particularly where it is used for parachute posts and as dubbing. When used on a dry fly it absorbs floatant and keeps your fly floating. Many companies claim to use poly yarn, however, fly tyers can easily test if it is genuine poly yarn, simply cut a 1” 25mm strip, scrunch it in your fingers and drop it into a glass of water. If it is genuine poly yarn it will dip below the surface then return to the surface film. It is this lighter than water feature that makes it an ideal dry fly material.
