I've got a pair of 5.11 Coverts on right now, with a blazer for the "casual Friday." They have a regular and zipped pocket on each side and two that are on-seam zipped and virtually invisible. They aren't as dressy as a pair of basic chinos but aren't far off. I have 2 pairs and don't wear the regular tacticals much at all any more.
