I bought this bag right before Interbike 2013, and I've been using it ever since. The shape is low-profile and unassuming, which is good, and the strap design is pretty comfortable under load. Honestly, it has a few more bells and whistles than a really needed, but after using the same Citizen Metropolis bag since 2001, it was time to change it up.
The roll top feature is pretty good to have in a pinch when you need some added volume, which brings me to a couple of drawbacks. This bag doesn't expand very much considering it's maximum height, which can make packing for an international trip a little difficult. When fully-loaded, the inside can be a bit like a pit of despair. But for everyday trips, it's no big deal. My other complaint is that the internal Velcro closure strap for the laptop compartment is a little too long. A weird complaint, sure, but when it hangs, it's chewed up a few expensive jerseys in my bag.
Overall, this isn't the be-all-to-end-all bag, but it's perfect for the slightly-demanding commuter.
