Semperfli Glo Bright Floss

Semperfli Glo Bright Floss is a high-visibility fly tying floss designed to give fly tyers bright, clean colour for traditional and modern fly patterns. Known for its strong colour intensity and smooth finish, Glo Bright Floss is widely used for tying salmon flies, trout flies, buzzers, lures and attractor patterns where clear body colour is important.

Made from high-quality fibres, Semperfli Glo Bright Floss lays flat on the hook to create neat bodies, tags and rib sections without unwanted bulk. It can be used directly for bright colour effects or blended with other materials to build more complex fly bodies. We have redefined the fluorescent floss devised by Tom Saville with a thinner floss capable of being used on smaller flies or giving better heads with finer layers to give a more attractive head or rib on a fly. Our team used our incredible computerised dyeing machinery have matched the original colors defined by Tom Saville and produced Glo-Bright Floss that has more use, can be used on smaller flies and is a step up from the original developed by Tom.
