Dark colors absorb more heat than light colors. Fabric has nothing to do with it. It's physics. There is a world of difference on a hot day, under-armour or not.
Take a black shirt and lay it flat on the ground on a hot day and place a thermometer inside. Leave it for 30 minutes and read the temp. Let the thermometer cool to the same temp it was before you put in in the shirt and then do the same experiment with a white shirt.
