Semperfli Boom Dubbing is a unique blend of up to 5 SemperSeal shades and 6 Ice Dubbings. This dubbing comes in 1.5gm packs with 100mm strands, ideal for predator and saltwater flies. The translucent SemperSeal and the bright flashes of Ice Dubbing create a new level of color and texture for fly tying. This longer-strand dubbing can be easily broken into smaller portions for streamers or other uses.
