This is the most convenient backpack I've ever owned. I literally have no idea how I survived before I got it. It is the perfect size for life's incidentals. Big enough to fit everything I need, but not so big I get bogged down by the ability to add in all those little unnecessary extras. It fits comfortably, with the weight distributed in a much more comfortable area than a normal backpack, and the zippers and straps all function well. Really an amazing pack! Highly recommended!!!
