Semperfli Hi Float Fibres
This is an incredibly fine floating fibre, one of the finest that we've had the pleasure of coming across. Great for use as the wings on your dry flies, indicator posts, and wings on Caddis, Hoppers (if you so desire) and stoneflies. Can be as an alternative material to deer, elk, calf tail, hackle tips and others.
To get the best result from them, give the fibres a brush out before use.
