Koolerpek Waterproof Business Backpack for Laptop Up to 15.6 inch Grey

It's really too bad because this backpack does so much really well. It absolutely fails on one of the key factors, it is not waterproof. Not even water resistant. After getting hit with a little rain I had to pull all my stuff out to prevent water damage. Water soaked through like it was nothing. I would have given the bag 3 stars otherwise because it does have some good features. Considering it really has no waterproofing at all, I'm deducting those stars because that is a crucial feature that is both lacking and advertised. It's one of the primary reasons I bought this bag and now I know I can't trust it.The bag is lacking for good little pockets. My last bag had lots of little places to put things and this one simply does have them. The front panel is kind of annoying to deal with as well and the front pocket has only a single zipper instead of 2 which make opening it a bit of a pain, the front panel (feels like carboard) also makes it annoying to open. Considering this pocket is holding all your pens and such, it's one of the most opened pockets and it's a great oversight to have it like this.For the good of the bag, I really like the deep waterbottle pockets. I can fit a whole Nalgene bottle in there. Also great for umbrellas. Every bag should have pockets like this. It also has quite a bit of room which is nice. I also really like the pocket on top which is perfect for sunglasses.

stitching on the external bungee connection for a carbiner broke when I lifted the empty bag when I first got it. Since I don't really strap anything to the outside I was not overly concerned. However after taking it on 3 trips now, one of the zippers on the main compartment has broken. I was a bit disappointed with the lack of securable pockets for storing things like thumb drives and change.The positive about the bag is that it has large compartments and holds my HP 8770w laptop with plenty of room. I could add clothes to the larger compartments if there was not enough room in my roller bag for some reason.

I bought this backpack to carry my laptop and some files around to and from the office on a daily basis. The backpack is lightweight and is made from waterproof materials. There are only a few pockets which I needed more than that to carry office supplies, chargers, files, laptop. The straps are VERY COMFORTABLE (Probably my favorite feature). The backpack in general is very large. Looks like your carrying your carry-on on your back. This has it's trade offs though. It's large and can carry a LOT of things. This makes it great for a weekend going out of town type of pack but for every day use it may be a bit big.Pros:Size-Very Large, so if your only goal is carrying around of a lot of things then this is perfect.Style-Has a very modern style to it. Doesn't look cheap at all. Seems very durable and will last a long timeDesign-It stands on it's own. I put my laptop and other things in trying to get it to tip over and it wouldn't. This is helpful in a office setting where you don't want you backpack spilling out with all the goodies your hiding inside.WaterproofStraps-Extremely comfortable and my favorite feature by far!Cons:Size-Very Large, most people don't need to carry a huge pack around so this can be bigI ended up returing this backpack because it's so large and there are not enough smaller pockets.

This is really great backpack but needs a little help. I've been using it now for about a week for work and it has held up for the most part. When I first received it, one of the zippers was stuck because the seam inside the pocket had loose threading. It also appears that the material scratches which came as a surprise since it feels like firm material. It also sounded like one of the stiches near a shoulder strap popped but I can't see anything loose and the strap doesn't appear to be weakened. This is the worst of my experience though. The bag is roomy and still keeps a slim silhouette. I have my MacBook Pro, iPad mini, work laptop, school books and some work tools all in it quite comfortably and no noticeable bulge. I'm also a really big guy and have always had a hard time finding backpacks that go over both my shoulders. This one does quite easily with plenty to spare along with the chest harness. I hope that the couple of things I described are all that is wrong with it and I hope to continue using it.

I unfortunately have to give this backpack a 1 star rating. I say unfortunately because I love the features of this bag and it has been a great bag for the past year. However, I purchased this bag less than a year ago (purchased 11/9/2016) and in that time the zippers on the small front pocket and the zipper for the middle compartment have broken, making the bag useless. The zipper on the front pocket broke about 1-2 months after purchasing the bag, and the zipper on the middle pocket broke this week (week of 10/22/17) while I was on a business trip.When I purchased this backpack (cost $45 at time of purchase) I chose this bag over several others based on several factors such as 1) spacious pockets for lots of storage 2) better water bottle holders than most backpacks 3) stylish enough to be used in a professional work environment. I assumed that a $45 backpack would have a longer life span than just shy of 1 year as it appeared to have a durable build and no major defects were mentioned in a majority of the amazon reviews I read on this product.In summary, this bag is a good bag while it lasts, but for the price point I expected a longer useful life for this product. If Koolerpek replaced the zippers on this bag with higher quality zippers, this would be a 5 star backpack in my opinion.
