Gearing up for chemical warfare

There are two kinds of fabric designed to protect soldiers from chemical and biological agents.

Hot and heavy Joint Service Lightweight Integrated Suit Technology, or JSLIST, is currently used by the military. It protects the skin with a layer of charcoal that absorbs chemical and biological agents.		Lighter membrane A suit in development uses a membrane that allows body heat to escape while toxic substances are repelled. It is lighter and more comfortable than the current suits in use.
