Our Pro Roller x-Series combines the refined look of fine luggage with the hardworking functionality of a mobile studio. Airline-compatible, (you can place the x100 and x200 in most overhead compartments*) these bags deliver the ultimate in security and organization along with a full set of premium features. Lowepro-designed oversized zippers with high-density pulls connect universally via a retractable cable to an official TSA LOCK** with a 3-digit combination - creating our exclusive Lock & Go System -;a streamline and secure means of protecting valuable gear. Our unique Reserve Pack feature provides a dual carrying option. Unzip the bottom of the roller to reveal an impromptu backpack, or to downsize in last-minute scenarios where a regional airline or smaller plan requires smaller dimensions for carry-on. A zippered front panel closes and secures the roller case for check-in or storage while the backpack is in use. A retractable TelePod features left-right operating buttons and a ¼"-20 threaded accessory mount, serving as a makeshift platform for lighting or shooting.
