Environmental suit

An environmental suit, also known as an EV suit, is a special form of clothing designed to be used for protection or life support in inhospitable environments.

With the advent of space travel came the need to perform tasks outside the controlled atmosphere of the space vessels. For this purpose, the EV suit was developed. As planets and other stellar objects came within the reach of Human space explorers, the EV suit became a necessity for exploring environments with different atmospheric conditions than those on Earth.
