I recently inquired about the size of the professional briefcase and I've been so excited and impressed about the product itself, that I'd like to look into more of that style. I love the look of both the roller and the duffel, but would also like the dimensions to help make a decision. I need some new luggage and I think the roller would be best, but again, just want to be sure. Many thanks on the briefcase recommendation. I love it!
