The weather resistant double coat consists of a long, flat, thick, outer coat of coarse hair, straight or slightly undulating, and lying over a dense, fine, woolly undercoat. The coat is more profuse about the neck and shoulders where it forms a ruff or mane, which is more pronounced in males so that it may fend off wolf attacks. The longer hair on the tail forms a plume. There is also feathering along the back of the front legs and along the back of the thighs, giving a "pantaloon" effect. The hair on the face and ears is both shorter and of finer texture.
The main coat color is white and can have varying shades of gray, red (rust), or tanaround the face (including a full face mask), ears and sometimes on the body and tail. As Great Pyrenees mature, their coats grow thicker and the longer colored hair of the coat often fades. Sometimes a little light tan or lemon will appear later in life around the ears and face. Being a double-coated breed, the undercoat can also have color and the skin as well. The color of the nose and on the eye rims should be jet black. Grey or tan markings that remain lend the French name, "blaireau", (badger) which is a similar grizzled mixture color seen in the European badger. More recently, any color is correctly termed "Badger" or "Blaireau".
