KOPACK Slim Laptop Backpack with USB Charging Port Water Resistant School Backpack Travel Rucksack 15.6 Laptop Bag

I bought the 17inch version of this backpack to use for vacation travelling so that I could store all my important electronic hand luggage (laptop, camera, charging cables, plugs, external hd, portable powerbank etc) and take it on the plane as cabin baggage - it would therefore need to be small enough to be within the cabin baggage standard size for the majority of airlines but also big enough to accommodate all my electronics. Fortunately to cut a long story short this bag is suitable for my needs and fits all my electronics into it comfortably with a little room to spare for other things. E.g. duty free shopping :-)When I first received the item it was flat and folded down so it looked tiny and I thought I had ordered the wrong product. But after unpacking it to my relief I found it to be of a good size, it is tall and thin, but this is expected as it claims to be able to hold a 17" laptop.The good parts- The bag looks good- It seems to be very well made and oozes quality.- It fits my 15.6inch laptop in the back pocket with room to spare. It is very easy to take out my laptop and simply slide it back in when going through airport security. The previous backpack I used for travelling was a real struggle.- it has two outside elasticated pockets for a drinks bottle and umbrella, The pockets are quite deep and i can comfortably fit a 'smart water' bottle in there.- there are two large mobile sized pockets inside which are quite deep so easily fit my thick and heavy external charger- one of the mobile size pockets is near to the usb port so it's easy to connect up to provide charging on the go via the usb port- the arm straps are so easy to adjust to make them tighter or looser - probably the easiest straps to adjust that I have ever come across- the arm straps are very comfortable and well padded, my backpack weighs about 9kg with everything in and it was manageable and comfortable to wear despite the heavy weight of it- the backpack has a band across the back of it which is a godsend when travelling. My wife has a mini 4 wheel spinner suitcase which she uses for her hand luggage, I can sit this backpack on top of her spinner suitcase and secure it with the strap to the spinners extendable handle, saving me the effort of having to carry the weight on my back, my previous backpack did not have this feature and I'd always be sweaty and hot during travelling due to having to carry the back pack through the airports across flight changes etc.- there is a hidden slot in one of the arms where you can slide in a debit or credit card for easy access, this is a very useful feature which I take advantage of- there is a pocket on the back of the backpack which you can store important items in such as wallet or passport etc, it's a little more discreet and gives me a bit more security for important items.-How could this be better?- There are no velcro or zip pockets inside so you cannot secure the items you put in there except the laptop which has a stretchy band with velcro on the end that you can use to secure the laptop into place- there are no pen holder sections inside the backpack which would be useful in preventing pens falling to the bottom and getting lost forever- although there is a usb output port for charging your devices there isnt a usb power input port which can connect to your power bank - this would be awesome as i could charge the powerbank without having to remove it from the back pack- there is no lock on the backpack which would be useful for greater security- there are no hanging loops on the backpack for hanging things like maybe a sunglasses case- I wish there was some sort of hanging loop inside the backpack so when travelling abroad I could put in my keys so when I get back home they are easy to locate.This backpack is almost perfect, there are a few improvements that could still be made as I have suggested above but I am happy with it so far so i can recommend this wholeheartedly and it gets 5 stars from me!

Okay, I rarely write reviews, but this item deserves one. Bought this item after much searching for a waterproof, high capacity commuter backpack that could take a 17" laptop, and it ticks all the boxes. Internal and external pockets of just the right dimensions in all the right places, high enough inside that you can fit a huge amount of stuff in if needed, deep enough to fit in really chunky items - takes my size 8 hi top trainers and a full size flask with loads of room to spare, strong, sturdy, well-made, and even internally waterproof. Had a liquid spill in the main compartment which did not seep through into the laptop section. Cannot find anything wrong at all - it even appears slimline when not stuffed. Best laptop backpack I have ever had, and I've had a few!

This backpack is bigger then I expected. Perfect for travelling. Nice and solid design. Smart anti-thief pocket. Definitely recommend.

Really comfortable and fits a lot for travel. I have gone abroad fitting every in this back pack. Love it.Stitched strongly and accurately. Quantity materials are used.

The quality of the bag is very poor. My (20 year old) son used this approx 12 times carrying his laptop to college, from the car park. I complained to the seller, but they described the fault as user error!The bag was an OK price, not cheap at £83, but I may as well have burnt the cash and bought a Targus!The top of the internal pockets pulled away from the lining in normal use. I am not sure how the seller can describe this as not under warranty when you see the condition of the bag externally.Do what I should have and spend a little more on a more reputable quality manufacturer. The seller's response (Karol Trade), was also poor.

The product arrived covered in mold! Very upset.

Good bag

How I use it:- Only during weekdays to carry my laptop (17") + headset + lunchbox + water bottle.- Extra careful (since a £2k5 laptop is inside, no need to tell you at which point I'm taking care of it)Bad parts:- Main zipper started to wear out after 6 months and had broken the following month.Good parts:- Great comfort: Carrying around 5kg every day without any issue.- Lot of space: You can fit few lunchbox inside. Two outside elasticated pockets: Very handy for water bottle / umbrella.- USB plug. Never used it, but can be interesting.If I recommend it?Depends. If you order it, you're not gonna be disappointed. At least for the first months but keep in mind the weak zipper. Other reviews can confirm this issue.
