Men's coldblack(R) UA Run Sleeveless T-Shirt - $29.99

WHY WE MADE IT: When the sun's blazing, ordinary fabrics-especially dark ones-absorb UV rays and heat up quick, meaning you sweat harder, fatigue faster & lose focus. But not anymore. UA uses coldblack(R) technology, a revolutionary fabric that reflects even the nastiest heat. So whether you're running a marathon in the desert or just playing 18 holes in the summer heat, black out the sun...and stay cool, dry & protected. Most fabrics-especially dark colors-heat up and become unbearable in the blazing sun. Well, no more. Revolutionary coldblack(R) technology makes dark colors act more like light colors, and light colors act like nothing else. It also has the benefit of protecting your skin from sun damage. Your new go-to running T-shirt for the sweltering sun.
