I purchased this backpack to ease the pain on my back from daily commutes to and from campus. It's a huge improvement from the old backpack I had, but after months of using it, I wish I had invested instead in a backpack that also has a hip strap, as these are becoming more readily available now and they take even more weight off of your back. I purchased my backpack in monoblue, which is a stunning color, but unfortunately it really shows dirt. The bottom of the backpack should have been made of thicker/darker material to make this less noticeable since backpacks can really only be spot cleaned.
