The Back-Roller Pro Plus is the XL version of the popular Back-Roller Plus touring bag. With a volume of 70 litres per pair, it offers almost twice as much stowage space. Its also the first Ortlieb Back-Roller with an additional front pocket. Although not waterproof, the pocket is unusually practical, offering 4 litres of space for water bottles, sunscreen, wet things, and other items. The durable Codura fabric gives the bag a noble, woven-fabric look, and is also completely PVC free. The proven roll closure keep the contents of the inner compartment clean and dry at all times. Thanks to the ingenious QL2.1 system with its self-closing hooks, you can conveniently mount your bags on almost any bike rack.Specification:Fabric: PS36C
