Under Armour makes the world's best cold-weather products. Nobody disputes that. But we're maniacal about warmth. We're never satisfied. So, we set out to invent something new....the best insulation system ever created. What we found was that heat loss is the glaring weakness in today's insulation technologies. Just because something can make you warm doesnt mean it can keep you warm. Our research led us to a strange place: Stealth Bombers. They're coated with a ceramic material that absorbs electromagnetic waves, which is why they are invisible to radar. And electromagnetic waves are actually a form of heat... which means the ceramic material absorbs heat. While investigating heat loss, we also turned to infrared imaging, which detects and pinpoints heat loss in insulation systems. The possibilities of the ceramic material and the visual proof provided by infrared imaging were the combined spark that inspired out latest innovation: Coldgear Infrared. A soft undetectable ceramic coating - the pattern - on the inner layer of the garment acts as a living breathing body warmer. The coating seeks,absorbs and retains your own body's hear, so Coldgear Infrared keeps you warmer longer.. with no extra weight or bulk.
