A tipi (also tepee and teepee) is a conical tent, traditionally made of animal skins, and wooden poles. The tipi was used by the nomadic tribes of the Great Plains in North America. Tipis are stereotypically associated with Native Americans in the United States in general, however Native Americans from places other than the Great Plains mostly used different types of dwellings.[note 1] The tipi is durable, provides warmth and comfort in winter, is cool in the heat of summer,[note 2] and is dry during heavy rains. Tipis could be disassembled and packed away quickly when a tribe decided to move and could be reconstructed quickly upon settling in a new area.[note 3] This portability was important to Plains Indians with their nomadic lifestyle.Modern tipi covers are usually made of canvas. Contemporary users of tipis include historical reenactors, back-to-the-land devotees, and Native American families attending powwows or encampments who wish to preserve and pass on a part of their heritage and tradition.
