  • Very good, just short of Great

    This is extremely well-made, durable, and good-looking. I use it nearly every day. The laptop section, for TSA clearance, is brilliant. The large main compartment is great for papers etc, and there's a tablet pocket. There are a few pockets for "stuff" in the front sections, but I've found them to be laid out ineffectively, and have taken to carrying two zippered "pods" with chargers, adaptor cables, etc. My main issue is the lack of a sternum strap - the shoulder straps keep sliding down when I'm walking any distance in NYC. I recently found an add-on that might solve that - see
    As far as construction quality, this is exceptional. I tend to carry a lot of "stuff" but there's no sign on any seams weakening (as has happened with other backpacks).

  • Finally, the perfect bag

    I started traveling 50/50 time for work three years ago, and have been through three backpacks (including some well known brands), and this bag exceeds all those bags. The style allows for a lot of "stuff" to be included in your bag, while still having that ever desired TSA approved compartment making traveling so much easier at smaller airports where you must remove your laptop, despite your TSA pre-check status. That was the big confirmation point for me. My last bag - which ripped horribly on its last trip - had it, and it was a must. This bag is EVEN BETTER in that the laptop sleeve stays zippered, and the TSA flap allows for it to be opened without compromising any laptop shifting.

    The lifetime guarantee, though, was what sealed the deal for me. Having been through three bags, whose total cost was over the cost of this bag, made me confident that this would be the long lasting and LAST bag I would need. I will be increasing my Briggs & Riley purchases to replace other travel bags - including the carry-on which gets quite a beating.

    Thank you for such a wonderful backpack.

  • The clamshell that does it all

    This bag is robust, comfortable on the shoulders thanks to excellent padding and can accommodate my 17inch laptop and all the power cables. Also, it offers room for my Kindle, newspaper and my water bottle. The business bag doesn't get any better than this.

  • This backback makes all other rucksacks obsolete

    I have searched high and low for the perfect rucksack that met the considerable needs that I placed upon it. It would have to survive the jostling from fellow tube passengers, be filled to capacity without buckling under the weight of my personal items, and accommodate my 17 inch laptop while still feeling comfortable and offering essential lumbar support to my back.
    Finally, the lifetime warranty provides me with considerable peace of mind to know that if I ever encounter any issues with the bag that Briggs and Riley will replace it no questions asked.
    Put simply this bag renders all other backpacks obsolete.
