Very good, could be better...
Overall construction quality, materials, and design is excellent.
However, there are opportunities for improvement in a next version, IMHO:
• There should be at least a velcro strap to secure the laptop/tablet in the padded pocket, if not a full velcro flap.
• The zipper for the "secret" pocket on the back should extend the full width of the bag, and the inside of that pocket should extend upward behind the carrying handle to allow stowing larger flat items like many sizes of magazine, if not quite envelopes or folders for 8.5 x 11" documents.
• Presently, the provided charging cable allows a laptop or tablet in the bag to be charged from an external power source without opening the bag. But if the provided cable was routable between major compartments inside the bag with "portholes," a battery could be stored in any of the interior compartments and be able to power any device in the bag and/or outside the bag using the exterior charging port. This might require a slightly longer cable be provided, but these portholes would enable more flexible utility of the charging port feature to be realized. The battery I own is too large to fit in any of the pockets available to the cable, so the feature is much less usable.
• The pockets in the padded middle zippered compartment (one wide enough for my battery, and three narrow ones) don't take full advantage of the width available to them, so they can't accommodate, for example, a 2 meter USB-C cable in one pocket. This…
