The Back-Roller Pro Plus is the extra-large version of the popular Back-Roller Plus touring bag. With a volume of 70 liters per pair, it offers almost twice as much storage space. It’s also the first Ortlieb Back-Roller with an additional front pocket. Although not waterproof, the pocket is practical, offering 4 liters of space for water bottles, sunscreen, wet clothes, and other items. The proven roll closure keeps the contents of the inner compartment clean and dry at all times. Thanks to the ingenious QL3 system, you can quickly and conveniently mount your bags on almost any bike rack.
