Billingham Hadley Pro Camera Bag

I was looking for a new bag for my trip to Italy. A compact, durable bag to carry DSLR with couple lenses, tickets, passports, iPad, etc. The bag that I can easy take on the airplane, train or subway. The bag that can withstand museum crowds, bad weather, protect the gear and is not standing in my way when I am taking pictures. I know, a lot of other bags can do this trick, but Billingham Hadley Pro caught my eye.
