Interesting discussion I have been following it with and for my wife. It would seem it comes down to personal choice and habits. My wife currently has the BMW Comfort Shell jacket & pants which she mostly likes. I have a one piece mesh suit I wear for commuting, running errands and very short rides and a two piece I wear for travel and long day rides. On the bathroom stops, my wife made the comment she sometimes struggles with lowering her riding pants, sufficiently to do her business, so another potential issue to consider. Recently on a short lunch ride, I wore my one piece mesh and my wife commented on how nice it would be to jump out of the suit and leave it at the bike while having lunch, walking around etc.
