Can be used for dry flies, nymphs and streamers. A blend of multiple different fibers giving a great mix of textures. Enough flash to get their attention even in dirty water on darker days but not so much it won't work on a brighter day. The orange is a shop favorite for Salmonfly patterns. It makes for great collar material on streamers as well. It's light enough to stay ontop of bugger bodies and not mat them down.
