This new version of Ortliebs popular Trunk-Bag is equipped with the light and durable roll closure system: the mouth of the bag is simply rolled shut with no need for trouble-prone zippers. A great choice for commuting and touring. *Can this bag be used together with pannier bags?* It depends on the rack: if the rack has only a single set of rails at the top, simultaneous use wont work. However, on racks that have a separate "top platform" and a second set of rails a few centimeters lower, the Trunk-Bag can be used together with pannier bags. - Thanks to the Rack-Lock system the bag is simply pressed onto the rack and detached by pulling a release strap - Waterproof - Welded seams - Inner part contains large main compartment and small item pocket - Shoulder strap - Reflector - LED light loop - Max cargo: 10 kg - Made in Germany - 5 year guarantee Manufacturer's [manual](https://www.ortlieb.com/media/downloads/anleitung/trunk_bag_rc_toplock.pdf) (.pdf file).
