Easy to stow, easy to set up and easy to use: the padded harness system for the ORTLIEB bicycle pannier series. It converts a single bag of the pannier models into a waterproof Daypack and thus eliminates the need to take an extra rucksack along with you. Simply click in the panniers at the top D rings with the QL1 system or QL2 system, fasten the straps into the edge protectors of the bags with the two clips at the bottom, and your bike pannier has turned into a backpack! Roll it up and you will see that it takes up very little space when compressed. And at a weight of just 9 oz. 270g you will hardly notice it at all. Reflective stitching on the outside of the comfortable shoulder straps makes this product visible in the dark. A sternum strap ensures an extra secure fit.
