The shirt changes patterns when it detects air pollutants

The three shirts, made by Aerochromics, are each built to detect either carbon monoxide, particle pollution, or radioactivity. Basically, when the shirts find dangerous levels of pollutants in the air, they change color, displaying a bold geometric pattern and alerting the wearer.

The way the shirts work is pretty complicated. The shirt that detects particle pollution, for example, has two small sensors, one on the front and one on the back. When particle pollution is detected, the shirt activates heat pads that change the white dots to black. In the carbon monoxide-detecting shirt, contact with carbon monoxide initiates a reaction with chemicals in the shirt’s dye to turn its black stripes white.
