New York designer Nikolas Bentel has developed a range of patterned shirts that change colour in response to air pollution or radioactivity.
Bentel's Aerochromics collection of three cotton shirts has patterns printed in a colour-changing dye that Bentel claims has never before been applied to consumer clothing.
Each piece is named after and features a pattern inspired by the pollutant it reacts to, from carbon monoxide and particle pollution to radioactivity.
The Carbon Monoxide shirt functions in a similar way to a carbon monoxide spot detector, which features a patch that turns black when carbon monoxide is present and clear when the air around it is stabilised.
As carbon monoxide comes into contact with the shirt, the gas is oxidised by chemical salts in the dye, a process that changes the dye's colour to white as it loses oxygen atoms.
