Hends Microfibets are very fine synthetic fibers with tapered ends. They allow you to tie fly bodies that end in a fine point, while maintaining the proportions of the insect being imitated.
Hends describes them as a durable material that contributes to the buoyancy of dry flies. When tying, taking care to preserve the tip during cutting maintains the benefit of this shape: length adjustment is done at the base. The color of the fibers is then chosen to match the pattern’s design.
