Mouton lamb refers to the treated skin of a lamb that has been sheared. The hair of the skin is straightened, chemically doctored, and set with heat to produce a moisture repellent finish. This finish, along with subsequent dying, enables the material to be utilized in products intended to imitate more expensive furs, such as that of seals or beavers. Thus, mouton lamb has not been as popular as many other furs among the wealthy, but offers those with lesser incomes a chance to own fur coats and similar items.
