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!

It doesn't perform as I would want.Bought the bag to carry 15" laptop which it does fine. The pocket arrangement is good, could do with somewhere to clip keys and maybe just an outside flap pocket but I knew all that from images, description etc. The main problem with this bag is that is made from cheap materials. I read a lot of the reviews because usually they give an good indication of the product and they said things like big zips and quality and air gap. Unfortunately this is not the case, the things that pull the zips are big thats for sure but the zips themselves are small and cheap and you can feel it every time you use them, I wonder how long they will last. The bag is comfortable but because of the materials you start to sweat very quickly, the side zip pockets are horrible mainly because of the zips but also the material is stiff so getting in to them is a pain, would have been better with mesh pockets and no cover and some kind of organiser in them instead of just a stretchy piece of material.I own a few rucksacks, ones for hiking, ones for running, ones with water bladders, all quality products paid for with my own money and used regularly. I didn't really need another one but wanted a reasonable one for my new 15" laptop so didn't want to spend mega-money.Overall I would say this a £15 bag. The design is good, maybe a removable waist strap and an outside flap pocket would make it better from a design point of view but it's the materials that let it down. I bought this for £29.99 with prime delivery, no discounts or freebies for an 'honest' review. Would getting it free make a difference to my review? If all I wanted was freebies, then yes, but if I actually wanted a bag to do a job then no.So I am still on the lookout for a decent bag and by the time I buy another one I would have been better paying more money for a recognised brand in the first place.

After 10 months i have nothing but praise for this product.It has everything i was searching for in a new backpack, looks good in a urban/work setting, feels extra good and fits everything you will ever need.it has heen rained over, filled with all kinds of things of all shapes, dragged around and carried all the way to other continents and back.At first i wanted it for my daily commute, but it's so good i ended up using it for everything! Weekend trips, trekking escapades...10 months later not even a scratch, it literally looks like i had just bought it last week.The only con: The laptop pocket (inside the main compartment) does not fit laptops very well, laptop still fits if you dont use that part.The "secret" compartment at the lower back side is a blessing. It fits phone, wallet and keys, very cushioned so you dont feel anything.The cushioned back is very well made. no matter how full it holds wonderfully, feels comfortable, no sweating either. Great quality straps.The zippers are very strong, shame that the paint kinda fades after a while.By experience i can confirm it is waterproof; Neither rain, mud nor puddles ever ruined my precious cargo, i'd put a cover on it though.For commuting Is a must, for everything else it does the job well.I recommend it!
