Ortlieb Carrying System Bike Pannier

"The Carrying System Bike Pannier transforms your pannier into a comfortable backpack and makes your biketour as flexible and individual as you want it to be. When not in use, the practical carrying system can be easily folded or rolled up and stowed in your bike bag to save space. Whether on the bike or on foot, the carrying system flexibly adapts to your individual requirements, as it transforms the pannier into a comfortable backpack in no time at all. The breathable carrying system adapts ergonomically and allows air to circulate comfortably at the back. When it is not in use and should not get in the way when cycling, the practical lightweight can simply be folded away or rolled up small. To be able to carry the pannier on your back, the carrying system is attached to the webbing loops at the top with the Quick-Lock fixation and firmly pushed into the edge slots at the bottom with two plugs. Additional load control straps also make it easy to carry bags with auxiliary closures."
