This collection of masks is designed give an aesthetic warning if the wearer is running a fever or the concentration of allergens in the air exceeds a certain threshold. The pattern printed with thermochromic ink changes color when the exhale exceeds 27C.

The collection comprise a series of different prints and three different shapes of masks: the traditional surgical style, a wrap-around-scarf, and a full-face sinus mask. The latter also senses temperature increases of the forehead as well as around the mouth.

The idea is to create a stylish early-warning system at least for other people if not for the wearer.
