Semperfli Dry Fly Polyyarn- Polyyarn has been nicknamed by fly tyers world wide as 'floating yarn'. It is fibrous and beautifully buggy. Semperfli Dry Fly Polyyarn is a bonded dubbing on a rope. Its tight, fibrous bonding makes it ideal for dry flies. Not only does it float naturally but its fibrous design traps air to help your flies float. Dry Fly Polyyarn is durable and the color choices (including the single color or mottled options) means there are many natural colors. Dry Fly Polyyarn is easy to taper to a point by applying heat. With a very specific gravity / density of 0.91g/cm3 polypropylene yarn is lighter than water, which means that it floats. Many companies claim to use polypropylene yarn; a simple test you can reveal if the material is genuine. Cut a 1 inch / 25mm strip, scrunch it up in your fingers, and drop it into a glass of water. Genuine polypropylene yarn will dip below the surface and then return to the surface. Semperfli Dry Fly Polyyarn is great for creating detached bodies. 3.9 yards per spool.
