I originally gave this a 4 because I thought the quality could be better in terms of back and shoulder support. However, after using this backpack for pretty much everything (laptop, travel, picnics) for almost 2 years I have to say this is the best backpack I've owned and one of my best purchases ever. No issues and it's truly amazing how much it fits. And it is comfortable.
Overall, a very comfortable, roomy backpack and lots of space. Love to top handles. After a year, still looks new. Looks great and is comfortable to wear. Perfect laptop sleeve inside and useful front pocket and side water bottle pockets. Shipped to me in 3 days. Must buy backpack
