    GlossaryGuard Hair (Protective Hair)

    coarse, longer hairs forming the outer layer of an animal's coat

    Guard hair, also known as outer hair or protective hair, refers to the coarse, longer hairs that form the outer layer of an animal's coat. These hairs serve to protect the underlying softer, insulating underfur from environmental elements like moisture and dirt, and they often provide camouflage or signaling functions.
