How the Batsuit Works

First, we found out how the Lightsaber works. Now, Howstuffworks.com is telling us how the Batsuit functions.

The main element of the Batsuit is a modified, advanced infantry armor system called the Nomax Survival Suit. Like many pieces of the Batsuit, the Nomax Suit was developed by the Applied Science Division of Wayne Enterprises.

The Nomax Survival Suit is comprised of a neoprene undersuit much like a SCUBA diver wears. The undersuit basically functions as waterproof, light armor with temperature-regulating elements that maintain the body's temperature and keep muscles from freezing up in the field.
