This is a unique custom blend of Ice Dub and 3/4" to 1" acrylic staple fiber that Hareline developed along with well-known steelhead angler Greg Senyo. It's great for wings on streamers like the Montana Intruder, can be spun in a dub loop for a shaggy collar and can also be dubbed for bodies on larger flies. It's a great choice for all kinds of salmon, steelhead, and trout spey patterns.
