OGIO ALPHA Convoy 525 Laptop Backpack - Durable 17-Inch Laptop Bag with USB Charging Port, Water-Resistant Travel Backpack for Work, School & Business Commuters

Yes, it is a bit pricey.; but this is a great bag and I am very happy with it. If you want a good sized bag without looking like you are going camping, this is a good choice. I originally bought it for an overseas trip. During our sight seeing, I was able to carry layers for my wife and I, snacks, water, an APS-C camera, two lenses, tripod, batteries, and room for any souvenirs we bought. As a carry on, it can fit a lot of gear but still fit under the seat. I had a laptop, tablet, same camera and lenses with tripod, a jacket, and various small accessories. Since then I have been using it as a work bag, mostly just for carrying my laptop and accessories to and from work. For that purpose, the bag is much bigger than required, but it works fine. Looking forward to using it on my next work trip and the following vacation.Features I like:1. Deep side pockets with straps for taller items. Work great for any size water bottle or a tripod.2. A few interior pockets. Not an excessive number of interior pockets, but just enough to place key items to find quickly.3. Main compartments are big enough to be useful. Many bags have compartments that are only useful for papers, folders, or a couple text books. Who carries those anymore? These pockets fit all kinds of things. The main compartment easily fit my camera bag and any other bulky items I have. The secondary compartment fits several accessories and a sweater or light jacket.4. Cordura fabric - this is actually a really nice feature. It's rugged like nylon without being too stiff or scratchy. Even cheaper Ogio bags you see in stores like Target don't have this fabric and you can really tell the difference.5. Sternum strap: small touch but nice to have for longer days.6. Adjustable shoulder straps with load lifters: another nice thing to have when the bag is well loaded and getting heavy.7. Security pocket: a small hidden pocket, nice place to hide something you don't need regular access to, like a passport.
