I LOVE this backpack! It was a bit bigger than I expected it to be, but that turned out to be a bonus, not a bad thing at all. It's big enough to fit my 16" laptop and everything else I carry with me during school, plus still had plenty of room for my purse, a sweatshirt, and a few extra items, which was extremely convenient. I really like the amount of storage compartments it has, I'm able to just unzip the main compartment and have everything I need easily accessible instead of having to dig around blindly looking for things.
My favorite features though are the breathable mesh backing, as it's already over 100° everyday here in Arizona and it helps me avoid unsightly and uncomfortable sweat spot on my back from carrying it, and the extra comfy padded straps don't dig into my shoulders either. Plus it has a smaller zipper compartment on the bottom part that rests against my back while I carry it where I keep my wallet, keys and cellphone. Because of the location of the compartment, it keeps my valuable items out of sight and securely protected from pickpockets and other thieves, which has been a problem on my campus the last year or so.
I highly recommend this backback to anyone who is looking for a roomy school bag with lots of organization, or even to use a great travel or vacation bag, as it's fairly large and has various areas for all kinds of different items you would want to take with you. This backpack even has an external charging port that connects to a pouch you can carry a battery bank in, which I don't know how I ever went without. Anyone who goes anywhere and carries personal item with them, whether it's to school the office, work, travel, etc, this backpack has he room and features to be suitable for all of it. You won't be disappointed!
