This is finest floating fiber I have ever used. These ultra fine fibers are perfect for various dry fly wings. Use in place of hackle tips, quills, calf tail, elk, deer, flank feathers, poly, hi-vis fibers etc. Use for parachute posts, split up right wings, caddis and stonefly wings even on hoppers. NOTE...when using the Hi-Float Fibers for the ultimate floating brush the fibers out first.
