I was suspicious at first about whether or not this backpack would be big enough to carry as much stuff as I would want it too, so I was very pleasantly surprised to find that it has so so so much room for everything I think I need (which is probably more than I actually need). When I'm not carrying very much, it rolls down to be a pretty petite pack, but for running errands or long days it will hold absolutely everything I need. And the side-zipper is good for grabbing a water bottle, or for rediscovering all those tiny things that find their way to the bottom of bags. The straps are comfy, and I was also stoked to find that the sternum strap was well-designed and well-placed (something that some backpack makers miss the mark on, ahem). So yes, great backpack for everyday stuff as well as trips and errand running. Glad there's a lifetime warranty!
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.
