I absolutely love this backpack. Even when I don't have a lot to carry, I prefer this spacious beauty over any other bag I own. The fact that is has the ability to accommodate an impromptu grocery store trip while still housing my everyday items makes this bag my daily go to. The side zipper is one of my favorite features, I can easily grab my book or water bottle when I'm on the bus without awkwardly unloading the rest of my gear. The built in laptop sleeve is great; it keeps my device separate from my lunch, and provides additional padding when I'm not lugging my computer around.
