I wanted to like this bag, but the quality is really deficient. MountainSmith used a fabric with a coating that started peeling off after a few months. It peels off in particles, so now I find particles in my helmet, my shoes, etc. One of the straps was not sewn adequately, and it's only hanging on by a few threads now.
On the topic of design, the cube shape works ok if the bag spends most of the time in the car, but it doesn't make for a very ergonomic carrying shape. And forget trying to stuff it in a standard size locker unless you keep it mostly empty.
