A line of reactive clothing that transforms its pattern as increased levels of harmful particles in the air are detected, giving you added awareness of your surroundings. Using our Aerochromic dye, our fabric begins to change from black to white at 60 AQI (Air Quality Index). The shirt's pattern is completely revealed at 160 AQI. The shirts are made from 100% soft cotton. They are fitted for unisex wear. We see Aerochromics as the first step in creating an ecosystem of interconnected objects that will help us better understand, navigate, and protect our world. Every object, material and person must communicate with one another in order to better equip ourselves to solve the grand challenges we face – like climate change. Our clothing will be just one part of a larger system of connected objects. Each user will become a sensor monitoring pollution in real-time, and with much greater resolution than the current system of static monitoring stations can offer.
