I purchased this backpack to take advantage of its multiple compartments and neatly organize my belongings for a trip across the country. In order to write an accurate review, I waited until after I had returned from my trip to rate this product. Now that I am back, I can say with confidence that this is an excellent travel backpack!First, I would like to point out a few things that some people may consider "cons" depending on what you are using the backpack for:• The Bottom Has No Extra Padding. This is perhaps my only complaint. The rest of my backpacks have always had an extra layer of padding at the bottom, which this backpack lacks. It was not too much of an issue for me, as I mostly carried this back pack on my back or on the back seat of my car. But whenever I was out in the wilderness and I set it down, there was always the slight wear and tear that adds up to holes and cuts. However, in the couple of weeks that I used it, it was fine. This is mostly something to consider if you plan to use it heavily for months and years; otherwise, it is fine.• The "Limited" Capacity. While this backpack had more space than I expected it to have, it still does not have as much room as other backpacks do. However, that is just the tradeoff for getting a slim good-looking backpack. So, while you may not be able to pack it with multiple changes of clothes, you will easily be able to pack your laptop, toiletries, chargers, battery packs, sunglasses, (slim) food containers, a few bottles, notebooks, and maybe a few rolled up shirts. The key is to think in terms of Tetris, by which I mean, "how can I neatly stack everything to maximize the space inside?"That being said, the things I loved about this backpack, or the "pros," are the following:• The "Limited" Capacity. While potentially a bad thing for some people, this was actually a good thing for me. I love that the design of this backpack constraints its content to fit within its slim rectangular parameters. This was particularly beneficial when storing this backpack underneath the seat in front of me on plane rides when using it as my personal item.• The Design. I love every design detail of this backpack. Starting with the multiple compartments, I loved that I was able to use a pocket for my sunglasses, a pocket for sunscreen and hand sanitizer, a pocket for my battery packs, a pocket for my charging cables, a pocket for my snack, and a pocket for just about everything. I also really enjoyed having different sections for different things. For example, I placed food and drink items that could have potentially spilled, in the front section, my electronics and cables in the middle section (the one with the double zipper/ability to use a TSA lock), and papers/documents in the hidden back section (where you would put your laptop). Having everything separate not only prevented damaging my items, it also gave me easy access to my belongings as I knew where everything was (unlike other backpacks with only one section). Lastly, I loved that it is water resistant. I was in the east coast where it is not unusual for it to rain in the middle of the day for an hour or so, and while the backpack got wet, its content did not. I know that this is not supposed to be waterproof, but water resistant did just fine for me.• The Extras. I am writing this one mostly because it’s worth highlighting that this backpack does come with convenient extra features, even though I barely used them. The ability to connect your battery pack (via an included USB cable) to an internal plastic port, where you would then externally connect your charging cable to plug your phone, was admittedly nice, but ultimately something I used just one. If that’s your thing, you will love this feature. The tiny holes in the metal tabs of the double zipper where you can use a TSA approved lock where nice, but something I did not actually use. It was good to know that I could lock my backpack should I need to though. The holes at the end of the straps for you to adjust the tightness of your backpack were actually something that I ended up enjoying way more than I thought I would. That was a pleasant surprise. As for the hidden section, like I said before, I benefited from being able to store my documents separately in this laptop pocket (and not have them bend or wrinkle), but I did not actually us it to hide a laptop. It was nice though. Every time I passed through security and had my backpack checked (a total of 5 time), not once did an officer realize I had an extra hidden section. If it can fool officers, hopefully it can fool people trying to steal things from you. I should probably also mention that this backpack was comfortable, but I think most backpack are.• The Style. Finally, the obvious and perhaps the reason why you are looking into this backpack in the first place, it is sexy. What is more, the pictures actually do this backpack justice. I was a bit nervous that some professional photographer might have enhanced the looks of this product when posting it on Amazon (the way McDonalds has gorgeous looking pictures of burgers in its Ads but never actually look nowhere near that good when you actually purchase them), but that was not the case. The backpack actually does look amazing in real life. As such, please buy this product with confidence knowing that you will receive what you are looking at on your screen.In conclusion, this is a great backpack! If what you are looking for is a very spacious backpack, you may be better off purchasing a duffle bag. But if you are looking for a decently spacious, stylish, well designed backpack with the ability to charge your phone (as long as you own a battery pack), then the Kopack Laptop Backpack is the way to go!Overall, this is probably the best backpack I have ever owned. I hope that helps!
