This bag is rad. Not too big for a few books going up to campus on m'bike. Not too small to comfortably accomodate a twelver. The pockets. The shoulder pad. Bueno! Awesome for biking around town without being too heavy. My second Crumpler bag, and still impressed.

The material quality of this bag is really fantastic and the main pocket is quite simply put massive. Every time I go to pick this up I'm slightly worried that I'll find 10 or 11 clowns inside it. But that said, the main pocket might also be too big if what you're carrying isn't itself quite large. For transporting a whole case of beer or an infant rhinoceros, it would be fine - but smaller objects (books, etc) will find themselves shifting with potentially uncomfortable consequences.

With some practice tho, managing the bag becomes second nature and everything else about it (material quality, style, etc) yields plenty of rewards. Its the bag you want on the bike or on campus.

And 4/5 only because I don't believe in giving 5 stars unless i honestly believe the thing i'm reviewing cannot be improved upon.

It’s a really great bag with lots of room but isn’t overwhelming when it’s empty. It’s perfect for school. I put my laptop, 2-3 books and all the other crap I carry all the time. It’s an awesome bag.

This is a rock solid bag. Fits well while riding my bike and holds a lot. Great price too.
