The Aleut people developed in one of the harshest climates in the world, and learned to create and protect warmth. Both men and women wore parkas that extended below the knees. The women wore the skin of seal or sea-otter, and the men wore bird skin parkas, the feathers turned in or out depending on the weather. When the men were hunting on the water, they wore waterproof parkas made from seal or sea-lion guts, or the entrails of bear, walrus, or whales. Parkas had a hood that could be cinched, as could the wrist openings, so water could not get in. Men wore breeches made from the esophageal skin of seals. Children wore parkas made of downy eagle skin with tanned bird skin caps. They called these parkas "kameikas," meaning raingear in the English language.(Aleut Corp. Web.).
