Fallow deer hair is relatively coarse and hollow, making it buoyant and ideal for creating floating flies. It typically comes in natural shades of brown, tan, and white, with some variation depending on the specific deer and the season.

It’s commonly used for tying wings, tails, and bodies of dry flies, as well as for creating realistic-looking legs and antennae on nymphs and other patterns.
