I already had a Bear Komplex duffle for the gym - BEST gym bag EVER - and when I got a new laptop that didn't fit my Flag Nor Fail backpack (which is otherwise a great bag, maybe not quite as big overall as I might think ideal - I do tend to overpack regardless of the situation!), I found myself in the market for a new backpack. The Bear Komplex Commuter is IT. Plenty of room, super sturdy construction, the whole 9 yards. What else do you want?
