Military Uniforms Of The Future Will Automatically Turn Into Chemical Suits In The Presence Of Threats -- Popular Science
Next-gen combat fatigues could incorporate a new kind of breathable fabric that instantly turns into a protective shell in the presence of chemical or biological threats.

Researchers at UMass Amherst are developing a new nanotube-based fabric intended for use in military combat uniforms that protects grunts from chemical and biological agents. But unlike the cumbersome and (really, really) hot chemical suits the military currently issues to mitigate those kinds of threats, this material will automatically switch from a highly breathable state to a protective one, triggered by the presence of a chemical or biological threat. The uniform may well know the threat is present before the soldier does.
