The Army is on the lookout for a fabric that could adapt to different temperatures.

This “environmentally responsive” material would constantly adjust to outside conditions as well as body heat.

Wired Magazine says right now soldiers are carrying cold and wet weather clothing options that take up space and cuts down on flexibility.

The Army wants to use fibers that contain two metals bonded together in a time spring. As the temperature drops one metal changes its length more than the other, resulting in a curl in the fiber.

A whole shirt made of this material would actually change thickness as it got colder, providing more insulation and warmth.
