The fur of seals has two layers. The first layer is the closest to the body that are short, fine and very warm. The second layer are the longer fur called "guard hair' which is a waterproof layer.
Beginning in the 1790s, and especially during the 19th century, fur seals were hunted because their fur was so valuable. A select few species suffered dramatic declines, but are now recovering. Most species are now protected and hunting is mostly limited to subsistence harvest (for Native Americans and Eskimos).
