The Think Tank Airport International V 2.0 roller meets international carry-on regulations and features TSA-approved locks on the main compartment. An integrated wrapped-steel cable lets you lock it to something nonremovable in a press room or hotel — or to a tree. The supplied dividers can be swapped out for the low divider kit, which leaves enough space for most laptops inside the locked main compartment.

A retractable handle, in-line wheels, and a subdued black-on-black design make the Airport International look much like a regular carry-on bag — but it’s all business for the frequent-flyer photographer.
