DC Comics and DIESEL have joined forces to bring to you super hero undies! The range includes four unique boxers inspired by four comic book heroes: Batman, Joker, the Flash, and the Green Lantern. Like the superheroes themselves, each of these undies features a special, unique power. The Batman boxer, for instance, will reveal a secret armor all over the more you wash and wear it. The Flash print contains a thermo-sensitive print that will change and move as you wear it, reacting to your body heat. The Green Lantern print has a florescent treatment on it, with a special print being visible after it is exposed to light. And finally, the Joker print features a photo-print acid effect.
