Underneath all that signature white fur, polar bears are actually black and between their skin, which absorbs UV light, and the hollow tubular hairs on the outside of their coat, they are able to trap a lot of their heat. Which is good because the arctic has an average winter temperature of -30 degrees Fahrenheit!
