Powder soft and vaporous that sticks perfectly on the exposed surface of feathers, hairs and synthetic fibres giving them an unmatched floating ability. The fly must be perfectly dry before shaking it into the powder or the floating effect will be the opposite. It resists very good when submerged and it creates air bubbles that mimics the wing case of insects. It can be used on all flies: nymphs, emergers, dry flies and streamers. You can test various applications on different parts of your patterns to get particular movements on the water.-Easy to use 2 grams bottle with ermetic snap cap.-Insert the fly already connected to the tippet, lay the cap and shake well until all the fly is covered.-Do not introduce wet flies into the bottle.
