I like the Eurohalter, too, for it's coverage. It's actually my favorite cycling top. I prefer the fabrics they use that are a print, rather than a solid, because they provide a little distraction.

I'm generally a modest person, but I don't get too concerned about nipplage, at least not during workouts. If they show, they show. It's no big secret that I have breasts with nipples. I otherwise wear a lightly padded bra that keeps me modest in other settings.
