Rabbit hair is the fur of the common rabbit. It is most commonly used in the making of fur hats and coats, and is considered quite valuable today, although it was once a lower-priced commodity in the fur trade.

Fur is a thick growth of hair that covers the skin of almost all mammals. It consists of a combination of oily guard hair on top and thick underfur beneath. The guard hair keeps moisture from reaching the skin; the underfur acts as an insulating blanket that keeps the animal warm.
