This bag is GREAT! As a college student, I only need to carry my laptop, charging cords, a notebook or two, calculator, pencils, keys, and wallet. So why would I purchase an oversized backpack with hundreds of pockets when I could just buy a simple, light bag like this one? Especially if I'm just wearing it around campus?I searched for hours for a bag that was...well, simple--both in terms of storage AND looks. And I think this one fits that expectation perfectly. I would also recommend taking a look at the other bags this company sells.Space:At first, I was a little worried about the minimalistic design/feel of this backpack, but it holds everything I need. I have a 15.6 inch laptop with a protective sleeve, and it fits perfectly inside the laptop compartment. It's a little snug, but I've never had an issue with it not fitting. In the main pocket, there is room for a textbook and a couple of notebooks. There's even a nice little sleeve for a tablet. The front pockets of this bag make it easy to organize all of my smaller/essential items. It makes it easier to find things quickly when I need them.Weight and support:Even at maximum capacity, this bag is not heavy at all, and everything feels very secure. That was an issue I ran into with my old bag, so this was one of the first things I noticed. However, the part of the bag that rests against my back seems slightly stiff. I guess this just encourages me to stand with perfect posture, haha.Travel:I would definitely use this backpack as a carry-on bag in an airplane. There isn't much space inside, of course, but I know my laptop and other important belongings would be secure--which is important for travel. However, I wouldn't use it for carrying clothes/toiletries/etc., but that doesn't matter to me since I intend to use this bag for day-to-day activities as a student.Would not:I would not recommend this bag to someone who needs to carry an above-average amount of items. Lastly, I wouldn't recommend this bag to someone who is looking for an overnight bag or an outdoors/utility backpack.
