Polar bears maintain homeostasis in freezing cold weather primarily through their thick fur, which retains heat. Additionally, they have a thick layer of blubber beneath their skin that also helps insulate them against the cold. While their metabolism can adjust in response to environmental conditions, their fur and blubber are the primary mechanisms for retaining heat in extreme cold.
