One of the best bags out there. I have had it for about 2 years. It is very durable and doesn't wear out anywhere!!! I bought it with a lot of reservation because my laptop is 15.6 inches and I wasn't sure if it would fit or if I should go for the bigger version, because it says it fits up to 14 inches. Of course, I searched on YouTube, etc. but I couldn't figure it out. In the end, everything is great. It has many nice and smart compartments for an external hard drive, power bank, glasses, cables, mouse, and of course, it comfortably fits some books or notebooks, sandwiches, etc., all together with the laptop (it has a separate compartment for the laptop, you should know). A small bag with large compartments!!! It is incredibly convenient for 3-4 day trips, of course, if you decide not to bring a laptop, etc., and only pack clothes. It expands a little bit, but what can we do... Well, for school, work, and everyday use, it is the best thing!!!
