Space is a vacuum, so the astronauts would otherwise be exposed to extremes of temperature. The Sun's radiation in space is much greater than on Earth and would be far too hot. The vacuum of space, on the other hand, is effectively very cold.
Another reason for the multiple layers is to prevent loss of air from punctures caused by dust-sized micrometeorites, which can travel at high speeds through space.
