Review of the Fjallraven Kanken 15" Laptop backpack: The plastic buckles on the straps dig into my sides (5'11" 150lb) with heavy loads so it's not ideal. It's not so bad if you can get below 5kg, and if you are smaller then I would assume this wouldn't apply. The rectangular shape is obviously great for maximizing space efficiency and though it is 40x28x16 it can easily me crushed to fit into sizers if necessary. However, there is not much organization to speak of. Aside from the front pocket and the laptop pocked, it's just one large compartment. The carrying handles are great on longer walks or for carrying heavy loads. The one thing that is spectacular about the backpack is that it is extremely widespread and as a result doesn't mark you as obviously being a tourist, especially if you remove the logo with a seam ripper. Great for everyday use as well, such as groceries.

Overall, I can recommend the bag but it's far from perfect.
