I like
Eastbay's training shirts. I'm 5'8" and the shirts are long enough to not be an issue of rising up for me, though I couldn't speak for someone taller. They seem to be a little bit longer than the C9 shirts I have from Target. Quality is excellent, stretchier than the Nike Dri-Fit shirt I have. Great deal when you buy them in pairs ($12 or 2 for $20) and although I don't think they advertise it, every time I've purchased an Eastbay branded item the order ships for free.
