The Airport Roller Derby Rolling Carry-On Camera Bag from Think Tank Photo features a customizable interior that can hold up to two DSLRs with lenses attached or one pro sized DSLR with a lens attached, as well as additional lenses, flashes, and accessories and depending on the configuration, the bag can hold up to a 400mm f/2.8 lens, unattached. The bag also has two dedicated padded pockets for a tablet and a 15" laptop.
The bag has four sets of dual inline-skate style wheels that rotate, allowing the bag to easily roll sideways through aisles or through people in crowds. It also includes a cable and a lock for locking the zipper and securing the bag to a post. A rain cover is included to protect your gear in inclement weather.
The feet of a tripod can slide into a side pocket, while a strap holds the top of the tripod secure against the bag.
