Grizzly bears have thick fur that consists of two layers: a dense undercoat and longer guard hairs. The undercoat traps air, providing insulation and retaining body heat, while the guard hairs repel water and wind. This combination helps keep them warm in cold environments, allowing them to survive harsh winters. Additionally, their fur can also change with the seasons, becoming denser and thicker in preparation for colder temperatures.
