At Under Armour, we find problems and we solve them. The latest: athletes who perform in intense heat need to be MUCH cooler. Yes, we invented HeatGear®—the original fabric that keeps you cool, dry, and light—but we wanted to do more. That’s where coldblack® comes in. Most fabrics, especially dark colors, absorb heat. Well, coldblack® actually blocks the heat of the sun, which means you feel like you’re playing in the shade.
