Hareline Ice Dub is a 100% synthetic dubbing will work on flies for trout, salmon, steelhead, smallmouth bass and largemouth bass. We love tying our flies here with Ice Dub to add great sparkle and because it dubs easily. Ice Dub comes in a wide variety of colors so you can use natural colors for your trout flies and use brighter colors for attractor patterns when fly fishing smallmouth bass and steelhead or salmon.
