I never even heard of it but seems like the last year or 2 there is more and more people wearing it. I even saw it in some stores, and not cheap either. what is the quality like? They seem to be as expensive or even more then Nike. Worth to buy or not? The quality and design seem to be quite nice. But the U over another inverted U looks terrible, but the name Under Armour conjures some images of knight or some shit. I think its an American brand. SOme of their material look like Nike Dri-fit. Kappa looks better, or even Puma in terms of clothing design.
