The thread about the Nike jersey's made me think- what are the best running singlets I have ever seen. I'm partial to Nike, and have always liked the Internationalist singlet from about 1989-90 (black and yellow/green). I also really liked the Nike singlets from the early 90's I think, with the odd colored lines at multiple angles (pretty hard to describe, and I can't find a picture).
Of course, the fabled New Zealand black singlet is awesome

Any others? What are your favorite classic and more modern singlets (and any links showing them)?
