You heard correctly.  The respected German Club will don Under Armour next season and becomes the first major European Club to do so.  Me being an American I have seen Under Armour make its mark in every other sport, so to see it starting in football is no surprise.  I have not personally worn anything from the company, but have seen it on professional athletes in baseball, american football and lacrosse.  I have yet to hear any complaints.  Look for Under Armour and Hannover 96 to make a big splash with a unique kit once they unveil it.
