What does my under armor clothing do?
I have a white and a black under armor. I have two long sleeves and one T-shirt. All three are very thin and they don't have a turtle neck thing. The short sleeve and one of the long sleeve is white, while the last one is black. I can't look at them right now because they are in the wash and the tags never say shiit. What do they each do? Or do they both do the same thing? Does the color make a difference?
