There are three types of guard hair: awns, bristles, and spines.

Most common goat breeds, including dairy goats, grow this two-coated fleece. The down is produced by secondary follicles, the guard hair by the primary follicles. [1]

Camel hair has two components: guard hair and undercoat. Guard hair is the outer protective fur, which is coarse and inflexible and can be woven into haircloth.
