The Pro Roller X300 is a hardworking mobile studio-with a few inventive surprises built into its modern design. Airport-friendly and super-secure, it holds a notebook, and is filled with refined yet practical features, such as the Reserve Pack-a camera backpack that zips out of the hard case when a photographer needs to downsize. A zippered front panel secures the hard case for check-in or storage while the Reserve Pack is in use. The exclusive Lock & Go System features a combination lock and a retractable cable to keep gear secure. The Pro Roller X300 is a true companion for the photographer who needs to get gear safely and easily to each assignment.
