Workout garb that changes color when you break a sweat

While your obnoxious grunting and heavy breathing may suggest to bystanders that you're a total beast in the gym, Radiate Athletics' new workout shirts offer physical, visual evidence of your actual intensity, as they only change colors when your body heat rises to a certain level.

The collection of moisture-wicking, soil-resistant, anti-microbrial Spandex/nylon compression tops come in eight different colorways, and're incorporated with a special re-engineered NASA tech that changes the way electrons reflect light in the presence of body heat. This means it'll show you in real time which muscles you're targeting and where the bulk of vascular activity is, thus offering suggestions about which areas you might be neglecting.
