What it is
Hareline UV2 Strung Schlappen is a bundle of long schlappen feathers from rooster hackle that have a UV2 double-dye treatment. The fibers are soft and webby, so they breathe and pulse underwater instead of staying stiff. The UV2 treatment adds UV fluorescence and UV reflectance, which can help the material show up in moving water and lower light.
What to tie with it
Use it anywhere you want a long, flowing silhouette: palmer it for streamer bodies, wrap it as a collar, or tie it in as a full tail or wing to build bulk without losing motion. It’s a natural fit for big hackled profiles on the hook, especially when you’re trying to get that “alive” look on the swing or on a strip.
Flies and the fish they're for
Wooly Buggers tied oversized with schlappen are a classic way to give the fly more movement and a larger profile, and they get fished for trout and smallmouth in rivers and stillwaters as well as for other aggressive freshwater predators. This material also makes sense in large-profile saltwater streamers, where that soft, webby hackle helps a fly swim for species like redfish and striped bass. In spey-style salmon and steelhead flies meant for swinging, schlappen is used to add a mobile collar or shoulder that keeps working even at slower swing speeds.
