Today was my first commute with the Bike Bureau. I was very happy with it after one day. It was a bit more cramped than I thought it would be, but I packed plenty of stuff: 15" laptop, dress shoes, pants, shirt, tie, belt, underwear, socks, shaving kit, iPhone, blackberry, wallet, office id lanyard, and gym id. Everything fit and my office clothes didn't get too wrinkled. I had some room left over. The cotton duck is very stiff, but I have a feeling that it will soften and get more flexible which should make the bag feel larger. The latch mechanism was secure and easy to get on and off the rack. It rained on my way home and there was no hint of dampness inside the bag. The cotton duck material repelled water no problem and wiped clean with an old sock. The Bike Bureau is very professional looking so I was comfortable carrying it into the office. My only gripe is that it lacks a pocket on the outside for a water bottle. I ended up carrying the water bottle by hand, but I could have stuffed it inside the main compartment. All in all, I'm very happy with the Bike Bureau.
