This bag does a superb job of fitting a really tricky bag sizing space: what I would argue as the limit in upper size of a sling bag that can be worn comfortably. What you can pack into 9L is the limit of comfort in terms of weight for a sling design imo, and the bellroy delivers. If you want chic, excellent organisation, a really clever opening mechanism (that I love but others don't, YMMV), and a larger form factor that still sits comfortably and snug to the body, this is your bag.
