I bought this bag in the event that one (2 x Professional DSLR, in my case 1DX and 1D Mk4 each with a lens or a profile-DSLR with 2 or 3 lenses) is with "small luggage" go. Therefore my expectation was not that I can take as much equipment, but actually get only the essentials stowed. Positive also the possibility to combine the bag with the handle of a suitcase trolley's.
In this regard, the bag has my expectation fully met, hence an absolute recommendation!
A small notebook you get in the front pocket, in the rear pocket is for no space. Optimally, this solution is not, but it works. For a larger notebook is perhaps the Urban Disguise 60 Pro is the better solution, because the bag has a different shape.
