I recently traveled to China with this backpack and absolutely loved it. i was a bit worried it would only fit my 15'' computer however it also easily fits my 17''!!!!! It comes with a lock, an easy accessible charging area, and tons of storage areas. I may need to buy another of these for my wife since she now hates her bag compared to mine lol

So i've been looking for a sleek urban commuter's backpack that can fit my laptops and books and the bunch of random crap I always seem to have lying around in the deep dark abyss that is my purse. Well this backpack fits the bill. At first I was a bit hesistant to buy it because it seemed to be made for men, but i was like whatever i'm a strong independent woman who can use and wear whatever I want. Who cares if the style looks a little masculine? I was only worried that the size might be to big for my frame (at 5'2 many backpacks dwarf me). But hey it works and it's beautiful and it fits everything without making me look like a turtle.

I was looking for a low profile light backpack to safely store my 13" flip notebook, extra phone charger, wallet, all sorts of small electronics and accessories, water bottle, snacks and still have enough room left to shove a sweater or a extra layer of clothing inside. This little backpack is amazing. It looks great, made out of very handsome and upscale-looking outer shell material and provides enough pockets to keep everything I can possibly need neatly organized. I usually do not write reviews for normal 3-star products. I write when I am angry or extra happy. The Kopack backpack is excellent, very well laid out and thoughtfully designed. Side pockets use elastic inserts so they can stretch to accommodate umbrellas and regular water bottles, without hanging loose like an out sized sacks when empty. Backpack looks nice and tight. Nothing loose or hanging. Having a charging port is a nice feature that came in handy more than I expected. I highly recommend this product.

Let me list the ONE Con upfront. I do wish the backpack had some sort of loop on the top, where you could pickup the bag easily with your hand. You can use the handle that's a part of the shoulder straps, but I'm a bit worried (in the design itself) the stitching may tear, if I pickup the backpack with substantial weight in it. Now then, with that out of the way... everything else about the bag is perfect! I didn't buy this backpack for school, I bought it for work. I need to be able to carry my laptop (obviously), my lunch bag, and my drink cup/tumbler. The bag fit my 15.6" HP laptop with EASE. It also had PLENTY of room for my lunch bag. My drink cup fit nice and snug in one of the side pockets. Not only do I have zero worries it'll fall out, the interior lining of the pockets is a tough vinyl, so the condensation is no problem. Heck, I even put my umbrella in the other pocket. I really don't feel like I've done this bag justice. The material used to make the bag feels like high quality, durable, thick fabric. Not some thin nylon garbage, that'll rip in a few months. The shoulder straps are extremely well padded, with extendable straps, which have hard plastic loops at the end, making it super easy to lengthen or shorten the straps. There's numerous pockets/storage compartments to put just about anything you'd ever need, and the USB passthrough to charge your phone is a VERY nice touch. The zippers, as well as the zipper mechanisms are built solid. Other than the ONE con I previously mentioned, I honestly don't think I could've purchased another backpack, with such high quality, for less than $25.00. If there's one last thing I can say, it's that I'm the type of person who you REALLY have to impress, in order for me to take the time to write a review for your product. This backpack overdelivered in just about every way possible. You can stop searching, because you really have found the best backpack for the money.

I purchased 2 of these for my daughters who are starting high school. They found these and thought they looked neat, especially with the charging component. I have to say these are the coolest backpacks ever. We even had them monogrammed. They seem very durable which I like bc they will be throwing them around all day :).

I LOVE THIS BACKPACK!! This backpack is perfect for me!! It's lightweight and compact and it's large enough. I have been searching for a good backpack and have tried many but this is the only one that has met ALL of my needs. The ergonomic support and wide straps are GREAT! I also LOVE, LOVE, LOVE the security compartment for my laptop. I really do love this backpack.

Just got this today. Its pretty awesome. The fabric its made of looks high end. The zippers and pulls seem well made. The pulls are where some companies will cut corners to reduce cost. I'm able to fit my 15" and 14" laptops in the bag at the same time. The bag has lots of pockets. One of the coolest features is that they label the pockets with what they designed each pocket to hold. The bag also has an external USB connection. It's designed for an external battery pack, but i use it to connect to my external hard drive instead. One of the internal labels is for a pocket to hold the battery pack which is where I stash my external drive. This is my new every day backpack. I'm able to fit my lunch bag inside and my insulated water bottle outside along with carrying my Note pro 12.2 and my ultrabook. I haven't had a chance to take it in weather so I have no insight to how it would fare. With all the pockets I can store everything I take for my 10 hour days and have it all where I can easily get to it. The straps have a place you can hang your sunglasses which is where I clip my work ID. I can't wait to take it to work tomorrow.

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!
