How do the Inuit protect themselves from the cold?

Traditionally, all Inuit clothing is made from animal skins and furs. In the Islands region, seal skins, which can be waterproofed, are the most common and practical choice. For mainland Inuit, caribou skins were the most common clothing. The close fit of Inuit clothing was often the skin or fur of the animal. This way the fur blocked the cold air outside and people felt warm no matter how cold it was.
