I was at REI today and I did like that Novara Commuter and next to it was a KoKi Vespa commuter bag. I really liked it, mostly, but I think it would be too small for me. Here is a link:

It just felt expensive to try thinking it might be too small. Still trying to locate an Osprey Momentum I can play with in person to see if I like it.
