I rock a Chrome Citizen, I used to rock at North Face Big Shot backpack that worked awesome on my bike, the waist and chest strap kept it from moving around. But then I got hit by a car and busted my right clavicle so I gave in and got a Chrome, mainly because it had the buckle release and with a busted clavicle it hurt too much to take a bag off without one.
I dig the bag, very sturdy and holds all of my stuff with plenty of space.
