I'm currently interchanging daily between the Waterfield Vitesse and smaller Waterfield Cycling Musette. http://thewirecutter.com/reviews/our-favorite-messenger-bags/#day-to-night-commuter-bag http://thewirecutter.com/reviews/our-favorite-messenger-bags... Great for subway commuting, and great for casual situations too. Both bags give me good options to fit my 13" and 15" MBPs. No lifetime warranty, but they're well built. I do have a GoRuck that I use when I need something more robust.
