Semperfli Dry Fly Polyyarn Grayling Bugs Collection

Dry Fly Polyyarn Grayling Collection - 10 Spools

10 stunning spools of Sempefli's polyyarn in deadly colours specifically designed for grayling dry flies and bug.

Polyyarn has been nicknamed the 'floating yarn'. Fibrous and beautifully buggy, this is an easy to use and a must have fly tying material.

Its fibrous design traps air to help your fly float.

Durable and with many colour choices (including the single colour or mottled options).

Easy to taper to a point by simply heating.

Easy to use for beginners and experienced tyers alike.

With a very specific gravity / density of 0.91g/cm3 it is lighter than water giving it excellent boyancy.

Many companies claim to use polypropylene yarn, however a simple test you can do at home to check if it is genuine polypropylene yarn is to cut a 1 inch / 25mm strip, scrunch it up in your fingers and drop it into a glass of water. If it is genuine polypropylene yarn then it should dip below the surface and then return to the surface.
