This is the staple of all photography rolling bags. I don't think I've ever covered a pro game and not seen one. Just about every photographer I know with a rolling bag, uses the Airport International. This was my very first roller bag purchase in college. I have been using that same one for over a decade.
It fits easily on flights, packs a ton, and gets better with age as the material loosens slightly to can pack even more and still zip secure. Has a lock to both lock the items in the bag and a cable lock to lock your back to a table.
I'm still rolling around with the original. They are currently on V3.0 Shop on Think Tank Photo
