Well, I did want something streamlined and I do really like Under Armour gear, for quality, value. Firstly, these are so comfortable you’ll not know you’re wearing any trousers, you don’t know they’re there! For me, the fit is generous in the waist, I’d order a size down from your usual. As to fit, it depends what you want (and how slim your legs are!). I went a little extreme with these, ordering the « slim taper ». More like drainpipes. My preference personally is for the UA tapered, rather than slim taper.
