The build quality seems good at first but the zippers on these break very easily. When my first one broke, I bought another one because I like the feel and the number of pockets this backpack has and thought it was a one off issue or that I had damaged it. The second backpack broke within a year. I love the pockets and internal design of the backpack, but the zippers just keep breaking. If this issue were fixed, I would buy again. I am a moderate user (not super heavy items).
