The fur, which appears to be white, is actually made up of almost colorless, almost transparent hairs. The long, coarse guard hairs are hollow, letting the warming rays of the sun reach to the dark skin that acts as a solar heat collector.

The air-filled guard hairs also help insulate them from the cold temperatures. The hairs of the thick undercoat are also nearly colorless but are not hollow.
